摘要：A latch-type charge pump circuit is provided having first and second chargepump stages interconnected by an intermediate circuit node. The charge pump circuitincludes first pump capacitors respectively coupled between first and second enableterminals and respective first inner circuit nodes, second pump capacitors respectively

coupled between the second and first enable terminals and respective second innercircuit nodes, latch transistors coupled between each of the first and second inner circuitnodes and the intermediate circuit node, and a stabilization circuit having at least onestabilization stage coupled between the intermediate circuit node and the first andsecond enable terminals and connected to control terminals of the latch transistors forsupplying them with suitable control signals so as to ensure their correct turn-on andturn-off during a charge sharing period of the charge pump circuit.
