An Enhanced Recycling Folded Cascode Amplifier

A recycling folded cascode amplifier comprising a local common-mode feedback technique with NMOS, working in a triode region is presented. The proposed amplifier shows enhanced performance as compared to the recycling folded cascode amplifier and OTA based on the local common-mode feedback structure with increased gain, GBW without additional power dissipation. The proposed amplifier performance is verified by the LTspice simulator tool with TSMC 180 nm CMOS process parameters. Performance of this amplifier when compared with CFRFC amplifier shows 202.9% GBW, 15.1 dB dc gain improvement with 30 pF load. The proposed amplifier has low fabrication cost and less verification time.
