ABSTRACT:
A charge pump circuit includes switch circuit modules and current modules. The number of switch circuit modules that are coupled to receive current from one of the current modules is variable. The output current of the charge pump circuit increases as more of the switch circuit modules are coupled to receive current from the current modules. The net on-resistance of the switch circuit modules decreases as more of the switch circuit modules are coupled to receive current from the current modules. Charge coupling caused by the net parasitic gate-to-drain capacitance of switching transistors in the switch circuit modules is reduced at smaller output current settings of the charge pump circuit.
