Abstract

A high performance two-stage Operational Amplifier is presented in this paper having the specifications of less Area and wide bandwidth which is operated on low power i. e.1.3V supply. Miller capacitor with resistor is used for compensation which also significantly improves the bandwidth. Design of Operational Amplifier is demonstrated with only CMOS transistors. The Amplifier exhibits a gain of 59 dB, 1.25 MHz 3dB bandwidth, 605 MHz Unity gain bandwidth, 269 dB CMRR, 106 dB PSRR, 1.6 V/s Slew rate with the power dissipation of 0.43 mW.
