Switched capacitors

A switched-capacitor circuit includes a plurality of sequentially-operated switched-capacitors A first capacitor is arranged to be coupled and thereafter uncoupled to an input signal during a first time period. Thereby the first capacitor is charged to an input value in dependence on the input signal. A second capacitor is arranged to be coupled and thereafter uncoupled to the first capacitor during a second time period for charge distribution between the second and first capacitor. Pairwise charge distribution is possibly done with further sequentially-operated switched capacitors. A final capacitor is arranged to be coupled and thereafter uncoupled to a previous capacitor during the final time period for charge distribution between the final and the previous capacitor. The switched-capacitor circuit further includes selectively coupling the first and the second sequentially-operated switched-capacitors to an output circuit thereby enabling a desired weighting of the input signal to be attained.
