Abstract

This paper discusses design constraints for low distortion Operational Transconductance Amplifiers (OTAs) on integrated analog front ends. It also compares traditional OTA topologies and proposes a new OTA showing significant reduction on distortion for wideband applications, the comparison is presented on a 0.35μm CMOS process. The proposed OTA is designed for on-chip analog front ends for radiation gamma detectors on a 130nm CMOS process.
