Abstract
Aspects of the present disclosure include a digital-to-analog converter (DAC). The DAC includes an output node and a plurality of equal sized cell transistors. Each of the plurality of equal sized cell transistors represents a distinct bit, the distinct bits including a least significant bit (LSB). The plurality of equal sized cell transistors are connected to the output node. The DAC includes at least one control circuit configured to modify a back gate voltage of one of the equal sized cell transistors representing the LSB to adjust a current output.
