Abstract
Official abstract text for this publication.
A digital-to-analog (DAC) element may include a plurality of switches arranged to form two circuit branches between a current source and a first and a second outputs. The first circuit branch may include two switches defining parallel current paths between the current source and the first output terminal. The second circuit branch may include two switches defining parallel current paths between the current source and the second output terminal. A control circuit, responsive to an input signal that selects one of the circuit branches, may provide control signals to close one of switches in the selected circuit branch in a first portion of a clock cycle and to close the other of the switches in the selected circuit branch in a second portion of the clock cycle.
