Chip Design and Implementation of a High Performance Bio-Signal Amplifier

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 the important current-mode amplification circuit for bio system chips with research emphasis on single power supply, low voltage, low power, low noise and high CMRR techniques. The achieved current-mode amplifier can be applied to the amplification processing of bio-medical signals. In this project, the key research targets in one year are the chip design and implementation of a high performance current-mode amplifier with power less than 5uW and CMRR over 120dB. Many circuit design techniques are proposed in this project to improve the circuit performance of this bio-signal amplifier. As compared to the most advanced prior art, the research target is very innovative and challenging. Those high performance circuit techniques for current-mode bio-signal amplification 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.
