Abstract
A driver circuit includes a series-parallel charge pump including switched capacitor cells, wherein the series-parallel charge pump generates coarse signal steps at a first output node and a second output node; a flying capacitor coupled between the first output node and the second output node; and a digital-to-analog converter (DAC) coupled between the first output node and the second output node including switched capacitors for generating a plurality of fine signal steps.
