Abstract
The present invention is directed to an improved CCD utilizing a potential gradient along the lengths of the various channels of the CCD during charge transfer to cause generated electrical charge to migrate along the length of the channel to a summing well. The potential gradient is formed by biasing the opposing ends of the electrodes overlying the lengths of the various channels with different voltages.
