Abstract
Aspects of the disclosure provide an operational transconductance amplifier (OTA) having an output stage. The output stage includes a first amplifier path configured to drive a first output current from a first power supply and a first resistor coupled between the first power supply and a source terminal of a first transistor in the first amplifier path. The first resistor is configured to improve a linearity of the OTA.
