Abstract
An apparatus and a method for regenerating charge packets representing logical information in a charge transfer device uses a pattern of field plate electrodes and impurity zones to perform arithmetic operations. To regenerate a charge packet it is first multiplied by a factor dependent upon transfer imperfections. Then an amount of charge representing a logical 0 is substracted from the charge packet. Finally, the magnitude of the charge packet is limited to the amount of charge representing a logical 1.
