Abstract
Certain aspects of the present disclosure provide a digital-to-analog converter (DAC). The DAC generally includes a plurality of current-steering cells, each having a bypass switch, and a resistor ladder circuit having multiple segments. Each segment may include a first resistive element and a second resistive element, the bypass switch being configured to selectively provide a bypass current to a common node between the first resistive element and the second resistive element.
