In the literature, Recyclic Folded Cascode (RFC) and Improved RFC (IRFC) Operational Transconductance Amplifiers (OTAs) are proposed for enhancing the DC gain and the Unity Gain Bandwidth (UGB) of the Folded Cascode (FC) OTA In this paper, an enhanced RFC (ERFC) OTA which uses positive feedback at the cascode node is proposed for increasing the DC gain without changing the unity gain bandwidth (UGB). This also has an additional advantage of decreasing the Common-Mode (CM) gain of the OTA. For the purpose of comparison, RFC, JRFC and ERFC OTAs are implemented using UMC90nm technology and studied through simulation. From the simulation, it is found that the DC gain of ERFC OTA is higher by 6dB, 1dB compared to that of RFC and IRFC OTAs respectively. The CM gain of ERFC OTA is lower by 31dB, 34dB compared to that of RFC and IRFC OTAs respectively for the same power and area. The Slew rate of ERFC OTA is higher by a factor of 1.14, 1.08 compared to RFC and IRFC OTAs. © 2012 IEEE.
