Abstract :
In this paper the design, fabrication and testing of a 10-channel array of identical amplifiers suitable for velocity selective electroneurogram (ENG) recording is described. The overall gain per channel is 10,000 and the total input-referred rms noise in a bandwidth 1 Hz-5 kHz is 290 nV per channel. The active area is 12 mm2 and the power consumption is 24 mW from ±2.5 V power supplies.
