In today's world operational amplifier is used in lot of application. The techniques for achieving high slew rate and high CMRR is by cascading the transistors. This paper focus is on understanding of Operational Trans conductance Amplifier (OTA) and Current Differencing Trans conductance Amplifier (CDTA) with its application as Instrumentation Amplifier (IA) for Biomedical application. We have designed Instrumentation Amplifier using CDTA to obtain high common mode rejection ratio (CMRR), high slew rate in comparison with OTA using PSPICE software.

Abstract


In today's world operational amplifier is used in lot of application. The techniques for achieving high slew rate and high CMRR is by cascading the transistors. This paper focus is on understanding of Operational Trans conductance Amplifier (OTA) and Current Differencing Trans conductance Amplifier (CDTA) with its application as Instrumentation Amplifier (IA) for Biomedical application. We have designed Instrumentation Amplifier using CDTA to obtain high common mode rejection ratio (CMRR), high slew rate in comparison with OTA using PSPICE software.
