Abstract:
A differential digital-to-analog (DAC) circuit that can include a reservoir capacitor and various switches to couple the bottom plates of the input capacitors, e.g., bit-trial capacitors, to reference voltages, e.g., REF+ or REF−. In this manner, the reservoir capacitor can be used to provide any differential charge to the input capacitors, e.g., bit-trial capacitors, and the reference voltages, e.g., REF+ and REF−, can be used to provide any common mode charge to the input capacitors.

Claim (Index 12):
The method of  claim 11 , wherein the input capacitors are bit-trial capacitors, and wherein transferring the differential residue charge from the dedicated reference capacitor to the pair of input capacitors when setting the pair of input capacitors in the differential configuration based on the decision of the comparator includes:\n controlling operation of a first set of switches to directly couple or cross-couple plates of the reference capacitor to a first plate of a first one of the pair of bit-trial capacitors and a first plate of a second one of the pair of bit-trial capacitors only when setting the pair of bit-trial capacitors in the differential configuration based on the bit-trial result to transfer the differential residue charge during the conversion phase; and coupling a second plate of the first one of the pair of bit-trial capacitors and a second plate of the second one of the pair of bit-trial capacitors to inputs of the comparator.
