Abstract: In this invention, a plurality of clock buffers are provided to supply clock signals to a charge transfer apparatus. These clock buffers are driven by the same basic clock which is introduced through a plurality of clock logics. Accordingly, even if the charge transfer apparatus is comprised of a multi-stage charge coupled device having a large number of stages, those clock buffers still have enough ability to drive the charge transfer apparatus with high frequency. So, the driving circuit according to this invention can drive a multi-stage charge transfer apparatus with keeping the excellent frequency characteristics, even if the charge transfer apparatus is driven with high frequency.
