摘要：This paper provides electronic implementation of electrocardiograph (ECG) circuit by using instrumentation amplifier (IA) as bio -potential amplifier in such a manner which reduces noise, commo n voltage, DC offset value and RF interference from the existing circuit.Noise and common voltage can be removed from ECG using driven right leg circuit or by using isolator circuit. DC offset can be removed by using integrator as feedback. In the differential amplifier part of IA, we can add single resistance, T-network or inverter circuit with integrator to improve impulse response. By using filters, we can reduce RF interference. In this paper, we have used instrumentation amplifier as a bio-potential amplifier
