ABSTRACT This paper presents a fully integrated and low power CMOS amplifier for neural signal recording. It consists of a band-filtering preamp and a current-mode instrumentation amplifier. The design approach and the noise optimizing are briefly discussed. A 0.6 μm CMOS technology is used for the design of the amplifier IC. The simulation shows that it has a pass band from 59Hz to 12.8 kHz and a mid-band gain of 80 dB. The supply voltage is ±1.25V and the power consumption is 180µW.
