Abstract

Some examples relate to a digital to analog converter (DAC). The DAC includes a digital signal input configured to receive a multi-bit digital input signal, and an array of cells. Respective cells in the array comprise respective capacitors. The DAC also includes a control circuit configured to, based on the multi-bit digital input signal, selectively induce one or more corresponding capacitors to discharge current to an output terminal of the DAC.
