Abstract
Operational Amplifier (op-amp) is a basic building block of many analog and mixed signal systems. Many different types of op-amp are used to achieve various functions, such as DC biasing, high speed amplifying, reduced voltage supply, high gain. To achieve these parameter successfully there are several techniques.The op-amp contains two stages to increase gain and improve slew rate, voltage swing, phase margin. In high resolution low voltage application where Thermal Noise and Op-amp output Swing are important then two stage op-amp is preferable to single stage. In circuits the gain provided by the input stage is not sufficient, so there is an additional amplification is required which is provided by second stage.
Keywords
Two stage Op-amp, CMO, Amplification.
