Abstract

This paper presents the investigation and optimization of a Recycling Folded Cascode Amplifier (RFCA) for designing a highly efficient and high-performance CMOS Operational Transconductance Amplifier (OTA). The proposed RFCA architecture leverages recycling techniques to enhance the overall gain, linearity, and power efficiency of the OTA. By analyzing the operational principles of the RFCA and exploring various optimization strategies, this study unveils the significant potential of this improved architecture in the context of CMOS OTA design. Simulation results demonstrate superior performance metrics, including increased gain, reduced distortion, and improved power consumption compared to conventional OTA designs. The findings of this study not only contribute to the understanding of RFCA-based OTA design but also offer valuable insights into the broader scope of recycling techniques in analog circuit optimization.
