Abstract

An analog processor chip developed for use in bio-signal capturing is presented. In order to get the physiological signal in the right bandwidth and amplitude, the processor includes the instrumentation amplifier, gain control stage and filters. It has been fabricated in a 0.5 μm CMOS technology, the measured results show the processor chip can capture the bio-signal with the frequency range of 0.5 Hz to 200 Hz, and has a total gain of 500, good agreement has been found between computer simulation and measured performance
