Design Analysis of the accuracy of measurement of small analog signals

    A range of 10 kg scale if to distinguish between changes in weight of 1 gram, the main

components of this scale often is a delta-sigma analog-to-digital converter. Design

Division temperature measurement accuracy of 0.01 degrees, delta-sigma ADC often become the

preferred solution. Delta-sigma ADC also be able to replace those in front

Plus there are the traditional type of a gain stage successive approximation register ADC. Due to

small changes in these data converters ideally suited for measuring the real world, so

Temperature sensors, scales, transducers, flow meters and other precision instruments, as well as

numerous other types of sensors are very suitable for the use of delta-sigma to the ADC.

    Delta-sigma ADC on the surface may seem very complicated, but in fact it is constituted by a

series of simple parts, precision data converters. Incremental

Cumulative ADC consists of two main components: implementation of the analog-digital conversion

of delta-sigma modulator and digital low-pass filter / extraction circuit. Delta-sigma modulator

The basic components (integrated operational amplifier, the summing node, the comparator / an ADC

and a DAC) shown in Figure 1. The balance of the charging circuit of the modulator is mandatory

than

Compared to the digital output of the bit stream to represent the average of analog input signal.

A DAC at the same time the comparator output is routed back to the modulator, using a low

Pass digital filter to process it. This filter to calculate the number of 0 and 1, and remove a

lot of noise, in order to achieve data transfer up to 24

Converter.

    A major obstacle to more digits resolution noise. For those who try to thermocouples, sensors

or other low-level signal source to identify

The designer of the level change in microvolts (µV), the noise will be a major problem. The

noise of the noise floor around by all unwanted external modulator

The source of the noise generated by the sum of the composition. And the noise floor is thicker,

the more difficult it is to detect you are trying to test real changes of the analog input

signal.

    Oversampling, noise shaping, digital filtering and decimation is the delta-sigma converters

used to reduce noise and produce high-resolution output data of the four kinds of important side

France. Assume that the input signal sampling frequency fS of a data converter according to the

Nyquist theorem of the data (the Nyquist theorem states) must fS

At least 2 times the input frequency (fIN = fS / 2). Oversampling is higher than the frequency of

the input signal frequency is twice the input signal sampling. A large oversampling

Sample (k) will produce a more fully digital bit stream, said. Composition of the bit stream "1"

or "0" the more, the number of the input signal approximation, the better

. Figure 2 shows the over-sampling to the sampling rate kx fS / 2 how to make the modulator to

the same amount of noise is extended to a wider frequency range. This greatly

Narrowed the noise floor in the frequency band of concern. The over-sampling rate for each

additional 2 times the desired signal-to-noise ratio (SNR) improve 3dB. The larger the SNR means

that the increase

The amount of cumulative converter can better distinguish smaller changes in the analog input.

The sound forming process, the more noise to force the passage of a higher frequency, as shown in

Figure 3. Then, the digital low-pass filter to remove high-frequency part of the noise,

This greatly improved SNR. The digital filter can also be used to greatly reduce the 50Hz, 60Hz

or other unwanted frequency noise.

    Help the blind see again

    Retinal repair technology can help the suffering from retinal degenerative diseases such as

macular degeneration may blinding the crowd to restore vision (Reference 1). Researchers

Member of clinical implantation studies do prove that implants can eventually make up for lost

eyes, using an implant, including a 15-channel

Incentive chips, discrete power components, and consistent with the eye the outer wall of power

and data receiving coil. Boston Retina Implant project researchers

Region in the retina of a pig implanted with an array, while most of the prosthesis (titanium

sealed electronic components box) attached to the outer surface of the sclera

, Or the whites of the eyes part. A spiral electrode array out of the box extends to the eyes of

the superior temporal quadrant (Figure 2). The system has an external video capture unit,

And a part of the send image data to the device implanted transmitters (Figure 3). A custom ASIC

image is converted to two-phase current pulse, its sent to the

The strength of the electrode array, cycle and frequency are programmable (Figure 4). The Minco

company also provides advanced flexible circuits for implants will help

To achieve this for the 1.7 million victims of such diseases of the eye pain people.

    Since the study began two years ago to do the clinical research, electronic technology has

undergone a lot of progress, improved miniaturization, reduced power consumption, and

Increase the level of integration, this effort is expected to form products, the FDA (Food and

Drug Administration) approval for use in humans. Examples of these technical advances

Child, including: Texas Instruments to comply with the Wireless Power Consortium Qi standard

wireless receiver and transmitter technology, the company is to provide improved load system

operator

Up to international standards of communication for wireless power transmission, AC / DC power

For this area, low-power wireless products.

    Another clinical study is the use of the photodiode circuit is expected to achieve high-

resolution retinal prosthesis. In this study, the Stanford University

The researchers are trying to study the active bias photosensitive circuits and passive

photovoltaic circuit (Reference 2). The University Department of Ophthalmology and Hansen

Experimental Physics Laboratory, vice

Professor DanielVPalanker said, he used a laptop computer processing the data stream from the

camera, a mini-LCD (similar to the video glasses)

The data obtained is displayed. Field of view of about 900nm wavelength near-IR (infrared) light

to 0.5ms interval to illuminate the LCD, which is equivalent to about 30? This pulse will pass

implanted in photovoltaic pixels receive the IR image, equivalent to 10?

. Each pixel is pulsed light is converted to a bipolar pulse current is proportional to carry

visual information to the diseased retinal tissue.

    Compared with the photosensitive system, the PV system additional power, which greatly

simplifies the design of the prosthesis, manufacturing, and related surgical procedures

The former requires active bias voltage. The researchers plan future studies to determine the

response of various retinal neurons such incentives.

    To help deaf people gain access to hearing

    Another field of development in Biomedical Sciences is a cochlear implant. The main objective

of these implants by electrical stimulation, or restore power safely

Can hearing (Reference 3). The implants included in the unit on the ear and an external processor

and a battery, an external unit with a microphone to pick up sound

Converting sound into the digital domain, digital signal processing and encoded into an RF

signal, and then send it to the antenna in the headphones (Figure 5). Doctors by

Surgery, beneath the skin is placed in the ear of a built-in receiver, a magnets out of it, the

headset is fixed. Sealed actuator contains the active electrical

Sub-circuit from the RF signal energy to decode the signal and converts it to current, and then

send it to connect the wires of the cochlea. Wire ends

The electrodes stimulate the auditory nerve connected to the central nervous system, these nerve

electrical pulse resolution sound.

    External language processor includes a DSP, a power amplifier and an RF transmitter. DSP to

extract the characteristics of the sound, convert it to

A data stream, the RF transmitter to launch out. DSP contains a stored image of the patient

information. Adaptation of the external PC program can be set

Or modify the stored image, and other voice processing parameters.

    The internal unit an RF receiver and a stimulator sealed. This internal implanted unit is

battery powered, so the receiver must

The RF signal energy. Then, the charge to stimulate the decoder RF stream, converted to current,

given to the auditory nerve at the electrode. A feedback system

Monitoring of implanted electrical neural activity, and these activities sent back to the

external unit (Figure 6).

    AdvancedBionics company has developed an implantable electronic platform, it offers more

channels, and generate a virtual pass through the current steering

Road capacity. The company's R & D vice president LeeHartley said the biggest challenge in the

development of complex sound processing sensor is one of increase in noise

Listening skills in listening environments. He said: "cochlear implant receiver for lack of

ability to distinguish between loudness level and the different frequency channels is all the

more

Challenges to improve the language understanding and music appreciation; we need intelligent

information from the noise isolated. "

    Hartley said that the next can greatly improve the cochlear implant system and the

performance of important areas, including: ubiquitous wireless connectivity and business

equipment;

Low power consumption, a more intelligent scene analysis algorithm, and so that patients can

receive a the clinicians cochlear implant technology, with the patient or physician

The home has nothing to do. He explained: "The technology trends in the industry is the system

architecture and service models, it will minimize the visibility of the entire cochlear implant

system.

Hartley is expected that the development of IC technology will provide wireless capabilities,

reduce system power consumption. He said: "I think the system design will continue to modular

recipients

According to their own changing needs of customize their own experience. "

    Signal processing has greatly improved the performance of cochlear implant. Sound can create

the model, make the voice become a cycle of the sound source, rather than voice has become a

noise source

. The resonant characteristics of the channel can filter the frequency spectrum of the sound.

There is another way, the sound source can be modeled as a carrier, while the channel as a

Modulator, show the opening and closing of the mouth or nose. The sound source is usually rapid

changes in the filter response is much slower (Reference 3).

    All modern cochlear implants, the internal unit to go through a percutaneous RF link

connected to the external unit, this is for the safety and convenience of the user

Think. RF link employs a pair of inductively coupled coils, not only transmit data, while the

transmission power. RF delivery unit there are some challenges, such as efficient

To amplify the signal and power, and maintain resistance to EMI. Its second function is to

provide a reliable communication protocol, including a signal modulation mode,

Bit encoding, frame coding, synchronization, and background telemetry detected.

    The cochlear implant RF design may have many conflicting challenges need to be carefully

weighed. For example, to extend battery life, power transmitters

Must be power efficient design. Thus, many modern implants are high efficiency class E amplifier.

Class E amplifier is non-line, they have

Waveform distortion, limits the data transmission rate. Another challenge is the efficiency of

the high power requirements to transmit and receive coils. RF systems in order to obtain

Power to work in its resonant frequency or a narrow bandwidth, but the RF system data

transmission Shique can not limit the bandwidth. In addition, although these

The equipment requires a high transmission frequency, but that would require large coil. In a

practical design available, the size of the transmit and receive coils must

Small to an acceptable level from the cosmetic point of view.

    The internal unit of the receiver and the actuator is the engine of the cochlear implant

(Figure 7). ASICs (dotted line) to perform critical functions, ensure safe and reliable

Electrical stimulation. It has a direct data path to the decoder to recover the digital

information from the RF signal, and errors and security checks to ensure

Paul correct decoding. Data distributor conversion multiplexer off state, after decoding the

electrical stimulation parameters sent to the programmable current source. Return to road

Diameter, including a background telemetry voltage sampler, used to read at some point on the

recording electrode voltage. Then, the PGA (programmable gain amplifier) ??amplification power

Pressure, the ADC converts it to the digital domain and stored in memory, then the background

telemetry sent to the external unit. ASIC also has a lot of control single

, Such as from the clock generation of the RF signal, until the instruction decoder. ASIC on the

integration of certain functions is not easy, such as voltage regulators, generators, coils and

RF tuning circuit, as well as the background telemetry data modulation, etc., but these areas are

growing.

    DAC and a current mirror composed of a current source, the amplitude information from the

data decoder, resulting in the excitation current. The current source must be very precise, and

also charge

Full of challenges. For example, due to process variations, the MOSFET source and drain the

relationship is not constant, the same time, the voltage difference between gate and source

control

Drain the amount of current. Therefore, the circuit requires one to adjust the network for fine

adjustment of the reference current. New designs have only DAC in order to obtain the required

Precise current, without the use of the potentiometer. Ideal current source has infinite

impedance, so many designers are using the cascade current mirror, to pay on behalf of

The price is to reduce the voltage margin, an increase of power consumption.

    These trade-offs must be carefully considered to achieve. Some cochlear implant more than one

current source, the older devices require a switching network, a

A current source connected to multiple electrodes. The new designs use multiple sequential or

simultaneous current source. In these designs, the P-channel and N-channel current source

You can generate incentives of positive and negative phase. The challenge is to match the P-

channel and N-channel current source to ensure that the balance of positive and negative charge.

Adaptive constant-current voltage can be reduced

Less power consumption, to maintain a high impedance.

    Engineers prefer using ASK (Amplitude Shift Keying) modulation, rather than FSK (frequency

shift keying) modulation, ASK simple, and

Low-power high-frequency RF signal. Thanks to the tireless efforts of a team of engineers,

scientists, physicists and entrepreneurs and cooperation, security and costs of co-

Management incentive has resumed the hearing of more than 12 million people worldwide. These

prostheses have evolved into other neural prosthesis development model, is expected to increase

several hundred

People's quality of life.

    Part II: brain, heart and lungs of people suffering from encephalopathy and lung and heart

disease benefit from the 21st century electronics, biotechnology and medical technology

collaboration.

    Momentum of biomedical electronics from the "baby boom" population aging and their health

care needs. This situation has stimulated new biotechnology

The rapid development of the technique, as well as innovation in the field of preventive

medicine, medical diagnosis, and treatment used. Later, the implantation techniques and advanced

wireless electronic media

Will help slow the rising medical costs of today's society, more health and longevity.

    The first section discusses the eyes and ears, this section will discuss the brain, heart and

lungs, and the development of technology to improve engineering, biological and medical

Between the bridge and enhance the function of these organs.

    This article will reveal the new device miniaturization, portability, connectivity, user-

friendly, security, and reliability is how to attempt to achieve this purpose,

To improve the fragile nature of human aging or sick / injury required by the organs in the

Ultrasound heavy volume of electronic touch screen new look at Intel's ultra this
 
    After the Spring Festival, with large orders of the resurgence of 2.3 billion yuan, Yu Shun

price January doubled to become the first bull stock ran out this year; in the previous half

Month or so, the ultrasonic electronic bulletin touchscreen Central Purchasing, which marked ZTE

2012, just somewhat less than the order size.

    However, compared to Yu Shun a quarterly loss, reported that pre-reduction, ultrasonic

electronic performance of many dazzling. With Angela technology, EPI precision

, As the company benefited from continued growth in the mobile communication terminal sales of

mobile phones, tablet PCs, which from the CCL and PCB manufacturers

Cut into the downstream of the industrial chain. Other touch screen companies with A shares,

ultrasonic electronics product line has been extended to the emerging super in this field.

    Touch screen products last year, a big bang

    The supersonic electronics industry originally focused Printed Circuit Board (PCB) field, the

companies produce both do the PCB material CCL, but also the production of the PCB.

    Since last year, go to the touch screen market for the company's focus. Ultrasonic

Electronics said, this change is with downstream customers products - ZTE

The structural changes appear.

    Ultrasonic electronic investment of 89.96 million yuan in 2010, construction of a capacitive

touch screen production line with an annual capacity of 45,000 square meters, the original plan

put into operation in July that year

, And then because of technical modification, augmented by a further 45,000 square meters / year

of new capacity. Mainstream smart phone screen size of 3.5 inches, approximately corresponding to

an annual

20 million to 24 million units capacity.

    The performance of the company are increasing. In 2011, the company achieved operating income

of 3.29 billion yuan, up 10.4 percent; net profit of 182 million yuan, up by

Of 12.57%. A quarterly revenue and net profit reached 934 million yuan and 67.039 million yuan,

an increase of 26.4% and 72.2%, respectively; and notice

Reporting the results pre-year increase of 50% to 80% growth due to the high-level HDI board

needs to capacitive screens for smart phones.

    Customer demand to promote the expansion

    A shares a large touch screen company, but each production capacity, customer structure and

position in the industry to differ materially. The high-end products dominated the largest

production capacity

Nature is leading Leybold Tech, over 50% gross margin to peer companies, bypassing about 20

percentage points; long letter did not disclose the shipment share of end customers

Samsung (microblogging), but has won, Sony, Panasonic and related certification; Ophelia light

started out in old-fashioned resistive touch screen, it was mainly Sky, Jin Yu

Long Cool in the low-end mobile phone customers, but last year announcement to get the Samsung

certification.

    Ultrasonic Electronics is the only one from the other areas of the industry chain transfer to

the company. And its clients have overlapping Yu Shun Electronics, ZTE communication

(microblogging), this year

The degree of cell phone touch screen product tender, ultrasonic electronics to get the order

amount is 779 million yuan, Yu Shun own estimates $ 23 billion.

    Have not previously been cut into the touch screen products, ZTE Yu Shun PCB products, major

customers; touch screen With the company production carve out last year, ZTE into

Its largest customers contributed 16% of revenue. ZTE nearly two years, mobile phone shipments to

enhance amazing, 2010, the total mobile phone sales and sales of smartphones
