This paper presents the design of a low-power high-CMRR CMOS instrumentation amplifier (IA) aimed for biomedical applications. The amplifier fundamentals were initially presented followed by its main building blocks. Simulation and experimental results were presented and discussed. The IA circuit was designed in AMIS 1.5 µm technology and manufactured through the MOSIS Service. The measured gain,CMRR and power consumption were 65dB, 120dB and 100uW respectively.
