ABSTRACT:
The present invention provides an apparatus for adding or subtracting an amount charge to or from a charge packet in a CCD as the packet traverses the CCD. The apparatus uses a “wire transfer” device structure to perform the addition or subtraction of charge during the charge packets traversal across the device. A pair of electrically interconnected diffusions are incorporated within the charge couple path to provide an amount of charge which can be added or subtracted from packets as the packets traverse the CCD.
