Analysis and Comparison of Two Stage and Single Stage Operational Amplifiers Using 0.18µm Technology

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