Abstract :
This paper is to analyze and compare the typical two op-amp Instrumentation Amplifier (IA) and three op-amp IA used in bioelectric acquisition system. We mainly focus on the key factors of IA such as power consumption, Common Mode Rejection Ratio (CMRR), gain error and input noise. Brief conclusion about IA is given from the point view of application.
