Abstract

The invention may relate to a digital to analog converter. The digital to analog converter may comprise a plurality of controllable current sources and a control circuit. The plurality of controllable current sources may include a first and a second controllable current source. Each of the plurality of controllable current sources may be controllable between a first state and a second state. The control circuit may be coupled to the plurality of controllable current sources. The control circuit may be configured to control digital to analog conversion at a sampling interval. The control circuit may be configured to control a first state transition of the first controllable current source at a timing in the sampling interval different from a second state transition of the second controllable current source.
