Abstract
A CCD imager includes a plurality of photoresponsive elements producing signal charges in response to light, a plurality of scanning charge transfer elements, each having a gate electrode, for receiving signal charges from the photoresponsive elements and for transferring the signal charges, and a plurality of serially connected inverter circuits, the outputs of respective inverter circuits being connected to corresponding gate electrodes of the charge transfer elements. The charge transfer is completed within the delay times of the inverters so that the charge transfer for all scanning elements can be completed without the mixing of charges from potential wells beneath adjacent gate electrodes.
