Abstract
A multiplying digital to analog converter includes first and second inputs for receiving first and second differential input signals. A differential amplifier has first and second differential input nodes and first and second differential output nodes. A first capacitor is coupled in series with a first switch between the first differential input node and the first input. The first capacitor is further coupled to at least one reference voltage supply node via one or more further switches. A second capacitor is coupled between the first differential input node and the first differential output node. A third capacitor is coupled between the first differential input node and the first input.
