Abstract
An analog differential voltage circuit is disclosed that enables the combination of a plurality of voltage signals in the analog domain of a CMOS processing system prior to being received by a differential amplifier and prior to being digitized. By programming the column decoder to read out a plurality of column buffer circuits, a plurality of linear operations (e.g., addition, substation, averaging, weighted, sum) may be performed on the plurality of analog voltage levels prior to their being digitized.
