Abstract: A digital to analog converter (DAC) includes a plurality of DAC transistor devices having an input side configured to be selectively coupled to a system voltage based on a digital input signal and an output side configured to provide an analog output signal, a plurality of non-DAC transistor devices coupled to the input side of the DAC transistor devices, the non-DAC transistor devices configured as variable resistances, and a control circuit configured to adjust a bias of the non-DAC transistor devices.
