摘要
Recently introduced MOS-FGMOS split length cell has been used to increase the DC gain of a fully differential op amp. Resultant proposed opamp structure exhibits gain of 97 dB and unity gain bandwidth of 400 MHz with power consumption of 1.2 mW. An opamp design has been verified with Cadence Spectre using a 130 nm technology at 1.2 V and has a slew rate of with a phase margin of 78 degrees.
