ABSTRACT:
The present circuit is applicable to buried channel charge coupled devices (CCD's) of the type having an input circuit which employs a "skimming" technique for producing a charge representing an input signal. A given amount of charge initially is present in an input potential well of the CCD and an amount of charge representing an input signal is skimmed therefrom for propagation down the CCD, leaving behind a residual charge which continuously remains in the input potential well. The gain of the input circuit of the CCD is controlled by controlling the amount of this residual charge either in open loop fashion or by means of feedback. A comb filter suitable for separating the luminance and chrominance components of a television signal which includes this circuit is also described.
