摘要:
A multiple staged charge pump network with staggered clock phases for pumping a first voltage to a second voltage with high current capability. The charge pump includes multiple serial charge pumps connected in parallel, multi-phase clocks, input voltage and output voltage connectors. The multiple serial charge pumps have in each series a plurality of diode-connected n-channel MOSFETs. The first n-channel MOSFET in each series is coupled to the input voltage connector, while the rest of the n-channel MOSFETs are coupled to a pumping capacitor at their diode-connected gates. The clocks are coupled to the multiple serial charge pumps for generating a plurality of phases of clocks with each phase of the clocks being applied to the alternating n-channel MOSFETs in a series such that adjoining n-channel MOSFETs are not driven by the same phase of clock. The input voltage connector is coupled to the first n-channel MOSFET in each series of the multiple serial charge pump for providing an input voltage. The output voltage connector is coupled to the last n-channel MOSFET in each series of the multiple serial charge pump for generating an output voltage after the input voltage is switched-regulated through the multiple serial charge pump.
