Abstract

In this article, a differential amplifier with a moderate gain of 40.56 dB is achieved. The UGF of 46.985 dB and phase margin of 84.15 degrees with a low power consumption of 61.084 uW. It is designed by using 90 nm CMOS technology in CADENCE VIRTUOSO platform by applying a supply voltage of 1.2 V with an ICMR of −296.098 mV–1.158 V. The post-layout simulations are also carried out and the results are being compared to the pre-layout results. Finally, a comparison is also drawn with some recent works.
