Zusammenfassung:A latch-type charge pump circuit is provided having first and second charge pump stages interconnected by an intermediate circuit node. The charge pump circuit includes first pump capacitors respectively coupled between first and second enable terminals and respective first inner circuit nodes, second pump capacitors respectively coupled between the second and first enable terminals and respective second inner circuit nodes, latch transistors coupled between each of the first and second inner circuit nodes and the intermediate circuit node, and a stabilization circuit having at least one stabilization stage coupled between the intermediate circuit node and the first and second enable terminals and connected to control terminals of the latch transistors for supplying them with suitable control signals so as to ensure their correct turn-on and turn-off during a charge sharing period of the charge pump circuit.
