Embodiments of the present disclosure may provide a charge redistribution DAC with two sets of capacitors that provides a DAC output by sharing charges between a plurality of pairs of capacitors in lieu of charging the capacitors using traditional external reference voltages. The charge redistribution DAC may comprise a plurality of pairs of first and second capacitors that each has a first side and a second side, and a group of first switches and a group of second switches. Each first or second switch selectively controls connection of the first side of a respective first or second capacitor to one of a pair of output signal lines according to a DAC input word. The charge redistribution DAC further may comprise a group of bridging switches each connected between second sides of paired first and second capacitors. |
