Abstract
A digital-to-analog converter (DAC) includes a plurality of DAC cells, a mismatch error sorting circuit, and a dynamic element matching (DEM) circuit. The mismatch error sorting circuit generates a sorting result of the plurality of DAC cells according to mismatch error levels of the plurality of DAC cells. The DEM circuit shapes the mismatch error levels of the plurality of DAC cells according to the sorting result of the plurality of DAC cells.
