Abstract
A digital-to-analog converter (DAC) includes a first DAC core, a second DAC core, and a butterfly switch. The first DAC core generates a first output. The second DAC core generates a second output. The butterfly switch includes at least one of switch transistors and cascode transistors. The butterfly switch selectively connects the first output and the second output to an output stage of the DAC.
