ABSTRACT:
A regenerator circuit for charge coupled devices removes charges produced by leakage currents along the shift channel of the charge coupled device. The regenerator circuit may also remove echo signals which develop in the shift channel. For removing charge produced leakage currents at given intervals along a shift channel of a substrate, an electrode is provided adjacent an electrode of a shift element and at a side of the shift channel. A diffusion zone doped oppositely to the substrate is arranged at the side of this shift element electrode. An electrode which follows the electrode of the shift element in the direction of charge shift has a separate terminal. For removing echo signals developed in the shift channel, a further electrode is arranged between electrodes of oppositely facing shift elements in a CCD loop. A shift element electrode which follows one of the shift element electrodes on either side of the further electrode has a separate terminal.
