Zusammenfassung:Methods and apparatus for common-mode current removal in a digital-to-analog converter (DAC). An example DAC circuit generally includes a plurality of current-steering cells, a resistor ladder circuit coupled to the plurality of current-steering cells and having a plurality of shunt branches, and an adjustable resistance circuit coupled between middle nodes of the plurality of shunt branches and a reference potential node for the DAC circuit.
