Abstract
Switching circuitry for use in a digital-to-analog converter, the circuitry comprising: a common node; first and second output nodes; and a plurality of switches connected between the common node and the first and second output nodes and operable in each clock cycle of a series of clock cycles, based on input data, to conductively connect the common node to either the first or second output node along a given one of a plurality of paths, wherein the circuitry is arranged such that a data-controlled switch and a clock-controlled switch are provided in series along each said path from the common node to the first or second output node.
