A new transconductor based on MOS transistors operating in saturation is proposed. Linearisation is achieved in a common-source pair by driving the devices in a purely antiphase mode. Simulation results show that the proposed transconductor would typically exhibit less than 1% THD for input signals up to 5.7 V.
