Abstract

Operational Amplifier is one of most important imperative device in electronics. In our work we have designed operational amplifier using differential amplifier in first stage and common source amplifier in the second stage. This CMOS operational amplifier works at 3.3v supply voltage and simulation process is carried out using EDA tool in cadence virtuoso 180nm technology. Thereby transient response, DC response and AC responses are obtained for differential amplifier and common source amplifier separately and then the above said responses are obtained for combined stages of differential amplifier and common source amplifier which act as operational amplifier.
