This paper includes the design of Enhanced Recycling folded cascode Operational Transconductance Amplifier (ERFC OTA) in both strong inversion and moderate inversion. The primary motivation for the design is from standard folded cascade (FC) OTA. The biased current sources are not contributing to the Transconductance (Gm) of the OTA in the usual FC OTA. In the Recycling FC OTA, the currents are recycled and the biased current sources are made to contribute to the Gm of the OTA and so the Gm is increased. Gm is further enhanced in Improved RFC OTA by creating one more high impedance dc path to the RFC architecture. The design is implemented in 90 nm UMC CMOS technology.
