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 13):
The method of  claim 11 , wherein the input capacitors are bit-trial capacitors, and wherein transferring the common-mode residue charge from the reference voltage to set the pair of input capacitors when setting the pair of input capacitors in the common-mode configuration based on the decision of the comparator includes:\n controlling operation of a second set of switches to directly couple the reference voltage 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 common-mode configuration based on the bit-trial result to transfer the common-mode residue charge during a 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.
