Abstract :
Electrically active cells in the body produce a wide variety of voltage signals that are useful for medical diagnosis and scientific investigation. These biopotentials span a wide range of amplitudes and frequencies. We have developed a versatile front-end integrated circuit that can be used to amplify many types of bioelectrical signals. The 0.6-mum CMOS chip contains 16 fully-differential amplifiers with gains of 46 dB, 2mu Vrms input-referred noise, and bandwidths programmable from 10 Hz to 10 kHz.
