Abstract:
1. A signal charge transfer line which has been formed on a substrate and is formed to have a number of transfer electrodes, for transferring signal charge by application of transfer pulses to the transfer electrodes via electrode lines, wherein: the number of transfer electrodes are divided into transfer electrodes of a plurality of sets to each of which a common transfer pulse is applied; electrode lines for applying common transfer pulses to the transfer electrodes of the plurality of sets are formed on said substrate in common for each of the transfer electrodes of the plurality of sets; an output gate for outputting the signal charge transferred in the signal charge transfer line is formed on a final part of an output end of the signal charge transfer line; an electrode line for applying a transfer pulse to a transfer electrode in front of said output gate is inherently formed on said substrate independently of the electrode lines of respective ones of the plurality of sets, wherein the transfer pulses, which are outputted from two inverting buffer circuits connected in series, are applied to the transfer electrodes of the plurality of sets, and wherein the transfer pulse, which is outputted from a non-inverting buffer circuit inputting a pulse is outputted from the first inverting buffer circuit of the two inverting buffer circuits.
