摘要： A charge transfer device in which reduced capacitive loading is obtained by utilizing a double split electrode (as opposed to the conventional single split electrode). Charge transferred beneath the double split electrode is differentially sensed by two of the segments. The portion of the total charge beneath the third segment is simultaneously transferred along so as to retain a uniform charge density beneath the electrode as a whole. This device is particularly adapted for transversal filter applications where the differential sensing is relatively small for a large proportion of the electrodes.
