Design and Simulation of High Gain Two-Stage Operational Amplifier is essential and plays a Vital role in the Semiconductor Industry Now a days It has a Vast number of real life applications but we focused on Providing High Gain where as we require Higher Amplification Is needed. In this paper a two stage operational amplifier has been implemented using 90nm Cmos Process which operates at 1.5 V power supply and a bias current of 10μA is applied in 90 nm technology. The op-amp provides a gain of 78.9 dB, phase margin of 670, Common Mode gain of -31 dB, 103db of CMRR, an output slew rate of 34.7V/μs, the power consumption for the op-amp is 219μW for a load of 1pF
