  • Abstract
    This paper presents a high linearity operational transconductance amplifier (OTA) base on the technique of mobility reduction compensation, which achieves great linearity improvement and has wide input range at low power consumption. The third-order harmonic distortion (HD3) of the OTA is about -65 dB at 1 MHz for a 1.2-Vpp differential input. The OTA was designed by the TSMC 0.18-μm CMOS process technology. For 1.8-V supply voltage, the static power consumption is only 0.427 mW.
