Operational Transconductance Amplifier in 350nm CMOS technology

This paper presents transistor level design ofoperational transconductance amplifier in CMOS technology.Custom designed, circuit is to be built-in into the mixed-signal,switched capacitor circuit. Amplifier targets relatively high slewrateand moderate open loop gain with megahertz order gainbandwidth.Adopted architecture is discussed appreciatingapplication in switched capacitor circuits. Circuit behavior isexamined through set of simulations. Obtained results confirmeddesired behavior. Target technology process is TSMC 350nm
