Abstract
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.
