Abstract
A current steering digital-to-analog converter includes a plurality of current cells each including a current source circuit and a current switch circuit to selectively output a current in response to a first input signal corresponding to a digital signal; a dummy current cell including a dummy current source circuit and a dummy current switch circuit to output a current in response to a second input signal; and a current switch bias circuit coupled to the dummy current cell to track a first voltage of an internal node of the dummy current source circuit and configured to generate a first bias voltage applied to the current switch circuit.
