ABSTRACT:
A charge transfer apparatus which is capable of reliably improving the transfer efficiency of an output gate section while preventing the occurrence of coupling to output waveforms. A two-phase driving-type charge transfer apparatus is constructed as follows. Transfer clock .phi.H2 used for driving the stage one prior to the final stage of a charge transfer section is divided at a predetermined ratio through the use of two resistors. This causes the generation of drive pulse .phi.OG in phase with and of a smaller amplitude than transfer clock .phi.H2. A gate electrode of an output gate section is driven by this drive pulse .phi.OG.
