ABSTRACT:
Various techniques for merging charge into and splitting charge from CCD's are described. Specifically disclosed in detail is a racetrack shaped charge coupled device (CCD), provided with special input and output stations operating on the principle of progressive charge read in and readout. During read in (which is a special case of charge merging), charge is injected in the direction of prevailing charge flow in the main channel of the CCD, with the injected charge packets being transferred laterally into the main charge stream while being stepped forward in the channel. During readout (which is a special case of charge splitting), charge is transferred from the main channel to an auxiliary channel through a plurality of interconnecting ports and, as during read in, transfer of a given charge packet takes place over a time period during which the charge packet is stepped forward in the main channel through several storage sites.
