Abstract
As the complexity of integrated circuits increases, the demanding for system applications is more
and more urgent. Among them, bio-system chip is both an important and a new technology. Since
few bio-system chips are now available the development is very urgent for practical applications.
Therefore, this project is dedicated to important analog interface circuits for bio system chip with
research emphasis on low voltage, low power, low noise and high resolution techniques.
In the past two years, we have completed two research goals. They are (1) design and
implementation of high resolution and low power 1.8V, 18 bit sigma-delta modulator, and (2)
design and implementation of high CMRR and low power 1.8V bio-signal instrumentation
amplifier with 160 dB CMRR. In the next year, we will focus the research on the design and
implementation of a low power, small area and high resolution decimation filter for the low power
1.8V, 18 bit sigma-delta modulator. In this project, we plan to use two methods to optimize the
design of decimator. First, we partition the general decimator which has a high over-sampling rate
into three stages, and then we use the algorithmic design to optimize the design of the first stage
decimation filter. Secondly, we adopt a single multiplier accumulator without RAM structure to
implement the finite-impulse response (FIR) Half-band Filter.
As compared to the most advanced prior art, the research target is very innovative and challenging.
Those high performance circuit techniques for biomedical signal conditioning will be realized in
one year to meet the required design specification and time schedule. Development results of this
project shall be very innovative. Besides, this project shall be very helpful to both the academic
research and technical progress of microelectronics community as well as student training on
analog/mixed-signal biomedical circuit design.
