Patent abstract
A folded R-2R ladder current-steering digital-to-analog converter is disclosed. In the folded R-2R ladder current-steering digital-to-analog converter, each node in the R-2R ladder is electrically coupled with a plurality of current sources with different weights. Therefore, the numbers of the resisters and current sources can be reduced, and efficient power saving and the high-speed operation can be achieved.
