摘要

This paper reports on the design and simulation of a bioamplifier, which can amplify bio-signals in the range of 1Hz up to 10kHz while rejecting DC offsets generated at the interface between electrodes and tissue. The fully-integrated bio-amplifier was designed in the 2 metals/1 poly 0.7μm CMOS process from the on-semiconductor. The bioamplifier shows a gain of 39.8dB in the range from 100Hz to 6kHz. The area consumed by the amplifier is around 0.36mm² of chip area, and the power consumption of the system is around 37μW from a 5V voltage supply.
