ABSTRACT:
The invention relates to a charge-coupled device of the accordion type provided with a shift register for supplying accordion clock voltages on the one hand and with clock lines for supplying conventiional clock voltages on the other hand. The electrodes are alternatively coupled to the shift register and to the clock lines. The dissipation can be considerably reduced in this device. Moreover, the transport direction can be reversed in a simple manner, which is of importance, for example, in image sensors for smear suppression.
