ABSTRACT:
A programmable analog array (10) comprises an array (11) of cells, each cell including analog circuitry (12), a switch control circuit (18), and a digital storage element (16). The switch control circuit (18) receives a clock signal and sequentially configures the circuits within the analog circuitry (12) to realize different circuit functions in accordance with configuration data stored in different digital memory units (17A-17D) within digital storage element (16). During a time interval, the analog signals generated by the analog circuitry (12) before that time interval are stored in an analog storage element (14), which is constructed from a portion of a capacitor network (54) in the analog circuitry (12) and is partitioned into a set of analog memory units (56A-56D). Each analog memory unit (56A-56D) stores the analog signal for a corresponding phase of the clock signal.
