The enhancement of recycling folded cascode amplifier
The enhancement of recycling folded cascode (RFC) operational transconductance amplifier (OTA) is described in this paper. The proposed enhanced recycling folded cascode (ERFC) structure improves dc gain and unity-gain frequency of RFC amplifier. The ERFC OTA has been implemented using TSMC 0.18μm CMOS process and simulated with a 1.8V power supply and a 5.6pF capacitor load. Simulation results show that the proposed ERFC OTA achieves 27dB increment in dc gain (72.2dB versus 45.2dB) and about 11 times better in unity-gain frequency (66.5MHz versus 746MHz) compared with the RFC OTA.
