Abstract
A capacitor-based digital-to-analog-converter produces a level-shifted analog outputs by precharging respective sets of output-generating capacitors to different applied potentials and then floating a common output of the sets of capacitors such that charge is redistributed among the capacitors through the common output to yield, across all the capacitors, a uniform precharge voltage that falls between the different applied potentials.
