Abstract

This paper presented a method for the design of a high frequency CMOS operational amplifier. The OPAMP is designed using tsmc 0.18 micron CMOS technology which operates at 2.5V power supply. This is a two stage CMOS OPAMP which employs a miller capacitor. To design a two stage OPAMP is a multi-dimensional optimization problem where optimization of one or more parameters may easily result into degradation of others. The OPAMP is designed to exhibits a unity gain frequency of 2.2 GHz exhibits a gain of 54.11db with 60Ëš phase margin. Design has been carried out in Pspice tool.
