Study and Analysis of Power Dissipation and Different Operational Amplifier (Op-Amp) Parameters of BJT (741) Op-Amp and CMOS Op-Amp Using T-SPICE

Ashish Kumar Singh, Nidhi Goyal

Abstract: An operational amplifier (op-amp) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually a single-ended output. We can design operational amplifier using bipolar junction transistor (BJT) technology and Complementary metal oxide field effect transistor (CMOS) technology. BJT is the fastest technology and CMOS is the lowest power consumption technology. In this analysis I will cover various aspects of an op-amp like power consumption, offset voltage for small signal and large signal mode, input bias current, input offset current, gain and frequency response, maximum and minimum output voltage swing, slew rate etc. Operational Amplifier is important building blocks for a wide range of electronic circuits.

Keywords: operational amplifier, slew rate, DC offset, power consumption and T-spice
