COMPENSATION OF 1ST ORDER TRANSFER-INEFFICIENCY EFFECT IN A C.T.D.

摘要

"Compensation of the 1st-order transfer-efficiency in a C.T.D." Charge transfer devices exhibit transfer inefficiencies, so that a part of a transferred charge packet is left and lags the original charge packet. This results in smearing of the original charge packet, thereby adversely affecting the unit-function response and the frequency response of the charge transfer device. The invention provides a solution to said problem, utilizing a compensation charge derived from the original charge packet, which at a suitable instant is applied to a point where the residual charge is cancelled via a feedback loop.
