Abstract
A charge pump latch circuit is provided that includes at least one first and at least one second charge pump stage interconnected by an intermediate circuit node, and a stabilization stage connected to the intermediate circuit node and to control terminals of transistors of the first and second charge pump stages. The stabilization stage includes at least one first pair and at least one second pair of first and second enable terminals receiving suitable and distinct phase signals that ensure the turn-off of the stabilization stage during overlapping periods of the phase signals. Also provided is a method for using a stabilization stage to drive transistors in first and second charge pump stages that are interconnected by an intermediate circuit node.
