Abstract
A charge transfer device of the bulk CCD type is used as an electronic variable delay line for video frequency signals. Charge packets are formed by integration of the input signal current over the entire clock period of the clock signal. As a result, cross-talk of the clock signal to the input section does not affect the video signal to be processed. Furthermore, the nonlinear characteristic of the input current source is linearized by negative current feedback with the aid of an operation amplifier. The input section of the device includes a diffused input region and a first gate electrode for receiving an input signal, and a second gate electrode for receiving a substantially constant voltage.
