Abstract
In accordance with an embodiment, a digital-to-analog converter (DAC) includes: a W-2W current mirror that includes a first plurality of MOS transistors having a first width, and second plurality of MOS transistors having a second width that is twice the first width, where ones of the second plurality of MOS transistors are coupled between drains of adjacent ones of the first plurality of MOS transistors; and a bulk bias generator having a plurality of output nodes coupled to corresponding bulk nodes of the first plurality of MOS transistors, wherein the plurality of output nodes are configured to provide voltages that are inversely proportional to temperature.
