Abstract
A gain stage using switched capacitor architecture and suitable for a pipelined analog to digital converters provides for three pairs of switched capacitor banks whose use may be alternated so as to provide simultaneous sampling of two input channels for sequential gain operation without the interposition of additional circuitry in the signal chain from input to output of the gain stage.
