چکیده
In this paper we propose a new low-noise low voltage BiCMOS instrumentation amplifier (IA) with high CMRR and exempted from resistance matching. This IA is dedicated to nerve signal recording as a part of implantable prostheses. The IA design and the simulation with the BiCMOS 0.8 μm technology are presented .The gain is programmable by using a network of resistors. The IA features a common-mode rejection ratio of more than 100 dB. The equivalent input noise is 1.4 μV rms.
