Abstract
An integrated circuit including a charge-coupled device for accumulating charge in a potential well and pair of metal-oxide semiconductor (MOS) transistors connected to form a differential amplifier. The gate of one transistor is coupled to the CCD potential well. The integrated circuit is provided with means for coupling the differential outputs, the drain of each transistor of the differential amplifier, to the differential inputs of an external op amp. Means are provided for coupling electrical feedback from the output of the op amp to the gate of the second transistor of the differential amplifier.
