Abstract
A drive unit for a charge coupled device, which includes a plurality of transfer electrodes arranged to intersect a transfer direction of information charge, and stores and transfers information electric charge using potential wells formed in a semiconductor substrate by voltages applied to the transfer electrodes. As at least one of the transfer electrodes is used as a selected transfer electrode, the drive unit causes the at least one transfer electrode to undergo a cycle of switching from an ON state to an OFF state a number of times continuously to transfer the information electric charge.
Claims12
A drive unit for use with a charge coupled device, including a plurality of transfer electrodes arranged to intersect a transfer direction of information charge, for storing and transferring said information charge by using potential wells formed in a semiconductor substrate by voltages applied to said transfer electrodes, wherein at least one of said transfer electrodes is used as a selected transfer electrode, wherein said drive unit applies a voltage to said at least one selected transfer electrode successively switching from an ON state to an OFF state to thereby transfer said information charge.
A method for driving a charge coupled device, wherein when storing and transferring information charge by forming potential wells in a semiconductor substrate by voltages applied to transfer electrodes, at least one of said transfer electrodes is used as a selected transfer electrode, and said information charge is transferred by applying a voltage to said at least one selected transfer electrode successively switching from an ON state to an OFF state.
