Abstract
A digital-to-analog converter (DAC) is described having a digital input, an analogue output, and two capacitors. The DAC has a controller. The controller is configured to generate a switching sequence including at least two switch cycles dependent on the input value received on the digital input. If the input value corresponds to an odd number, in a first switch cycle during a switch cycle first phase, the controller switchably couples a reference voltage to a first terminal and a ground voltage to a second terminal of one of the two capacitors, and switchably couples a ground voltage to a first terminal and the reference voltage to a second terminal of the other of the two capacitors. During a switch cycle second phase, the controller switchably couples a ground voltage to the first terminal and the analogue output to the second terminal of both capacitors.
