ABSTRACT:
The input signal to a CCD register is sampled many times during one period of the multiple phase voltages employed to drive the CCD. The samples are translated to small charge packets which are added to one another during the one period to produce a sum charge packet which subsequently is propagated down the register. The higher frequency components, including noise, which are present in the input signal largely cancel during the charge addition process.
