Design of 30 MHz CMOS Operational Amplifier

CMOS operational amplifier is now an integral part of analog and mixed mode designs. In this article, CMOS op-amp with 30 MHz bandwidth is designed. This configuration of op-amps finds huge application in active filters. The op-amp showed the unity gain bandwidth of about 30 MHz and DC gain of about 56.94 dB and slew rate of about 29.9 V/µs. This circuit is designed using Cadence virtuoso environment gpdk 045 nm CMOS technology.
