Low-distortion CMOS transconductor

Abstract

A new transconductor based on MOS transistors operating in saturation is proposed. Linearisation is achieved in a common-source pair bydriving the devices in a purely antiphasemode. Simulation results show that the proposed transconductor would typically exhibit less than1% THD for input signals up to 5-7V. © 1990, The Institution of Electrical Engineers. All rights reserved.
