ABSTRACT:
Charge refreshment in a charge transfer device is accomplished by a charge comparator in which charge is ejected over the lower one of two potential barriers, one of the potential barriers having a height controlled by input charge packets to be refreshed, the other potential barrier establishing a reference level for the comparison. The device includes a bistable latch to increase the comparison speed, the feedback nodes of the latch being isolated from the output nodes of the charge refresher comparator so that substantially none of the output charge is diverted to furnish feedback for the latch.
