  • Abstract
    A new CMOS circuit is proposed for implementing an operational transconductance amplifier (OTA) based on the square-law characteristic of MOS transistors biased in saturation. Simulation results show that a total harmonic distortion of the output current smaller than 1% for differential input signals up to 3.8 Vpp and supply voltages of +or-5 V can be obtained.
