Two Stage Class AB Op-Amp for Video Applications

Operational Amplifiers are flexible and can acclimate to as many circuits as required. Our work deals with an op amp which we have designed using Class AB push pull amplifier for video applications. This push pull approach overcomes the drawback of a single stage op-amp which doesn't give enough output swing. We have simulated this CMOS operational amplifier with 180nm technology using Cadence Software. Performance parameters of an op amp such as Gain, Gain Bandwidth Product, Phase margin, Common mode Rejection ratio, Slew rate, Settling Time, Noise has been analysed in our work.
