Operational amplifier exists in many numbers of configurations. The there are many types of the Operational amplifiers. These are: two stage, single stage, three stage and multistage amplifiers. Identifying the better op amp is important to get better application. The better op amp will be selected by considering the performance parameters (DC Gain, Slew Rate, Power Dissipation, etc.) of op amp. In project work a two stage cmos and single stage CMOS operational has been compared and contrasted based on values of their performance parameters by using 0.18µm CMOS technology and the same power supply (5V). Based on these values, By comparing the performance parameters single stage CMOS op amp is more stable and operate longer duration of time than two stage cmos op amp with small energy loss; while two stage op amp produces the output which is twice larger than single stage op amp, and also the noise in the output of two stage op amp is less than single stage op amp. So to get more output it is better to use two stage op amps. By results and reasons suitable choices for high gain and high performance applications are two stage topologies.
