ABSTRACT:
A charge control circuit for bidirectionally transferring metered amounts of charge, selectively, through a transfer channel of a four gate electrode charge coupled device (CCD) is disclosed. The bidirectional charge control circuit is used primarily to increment and decrement metered amounts of charge respectively to and from a charge storage medium. More specifically, five electrical signals are generated to have varying potentials in accordance with predetermined time sequences. These signals are applied to the four gate electrode CCD in a selected one of two states to either increment or decrement a metered amount of charge therethrough to or from the charge storage medium respectively, in a predetermined number of five segments. One of the generated signals governs the metering of charge for each increment or decrement operation.
