Abstract
A semiconductor charge transfer device comprising: a semiconductor charge transfer element including a plurality of transfer electrodes on an insulating layer formed on a semiconductor substrate and a detection node formed on the semiconductor substrate; potential barrier means for signal charge packets transfer provided between the final stage cell of the semiconductor charge transfer element and the detection node; and a differential detecting circuit of flip-flop type having a drive transistor directly coupled with the detection node, wherein the potential barrier means provides a potential barrier against the low level of the detection node when the drive transistor is conductive.
