Abstract
A multi-bit digital-to-analog converter has a reference voltage generator generating a reference voltage with an offset voltage; a switched capacitor stage for generating a plurality of output voltages; and a switching sequencer controlling the switched capacitor stage operable to generate switching patterns for each output voltages, wherein each pattern has a charge phase and a transfer phase, and wherein for at least one output voltage the switching sequencer provides two switching patterns wherein each switching pattern contributes an offset of opposite polarity.
