  • Abstract
    In this paper a new CMOS operational amplifier using a Darlington pair based gain boosted technique has been enunciated. The proposed Opamp shows high gain as well as high UGB using capacitor compensation technique and proper biasing circuit. It is operated on rail to rail power supply of ±900mV. This amplifier is highly useful for wireless communications due to low power consumption, high bandwidth, high gain and high noise immunity. The designed operational amplifier gain is 89dB, bandwidth is 4.40 GHz and phase margin is 67O, and slew rate is 991.6V/μS. This circuit is designed using Cadence analog & digital system design tools of gpdk45nm technology.
