ABSTRACT:
A differential charge-transfer device for transversal filtering or delay line applications. It comprises: two charge-transfer channels which respectively receive the two signals, the difference between which is to be formed; an electrode common to both channels; means for sampling the signals in each channel, this sampling taking place at the same instants in both channels; a set of electrodes in each channel which, on the application of potentials of period T, propagate the samples to the common electrode with a relative delay equal to T/2 from one channel to the other. The signal representing the difference between the input signals is extracted at the common electrode.
