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 1):
A differential digital-to-analog (DAC) circuit comprising:\n a capacitor array including a number of DAC units, each DAC unit including:\n a pair of input capacitors configured to couple to a comparator; \n a dedicated reference capacitor associated with the pair of input capacitors; and a control circuit configured to:\n control operation of a first set of switches to transfer a differential residue charge from the dedicated reference capacitor to the pair of input capacitors when setting the pair of input capacitors in a differential configuration based on a decision of the comparator; and \n control operation of a second set of switches to transfer a common-mode residue charge from a reference voltage to set the pair of input capacitors when setting the pair of input capacitors in a common-mode configuration based on a decision of the comparator.
