Claim 11:
12. A current steering digital-to-analog converter comprising:
a plurality of first current cells each including a first current source circuit that generates a current according to first bias voltages, and a first current switch circuit that selectively outputs the current generated by the first current source circuit according to a second bias voltage and a first input signal;
a first dummy current cell including a first dummy current source circuit that generates a current according to the first bias voltages, and a first dummy current switch circuit that outputs the current generated by the first dummy current source circuit according to a third bias voltage associated with the second bias voltage and a second input signal; and
a first current switch bias circuit configured to generate the third bias voltage having a level adjusted to match an amount of a level change according to changes in process, voltage, and temperature (PVT) of a first voltage of an internal node of the first dummy current source circuit.
