Abstract:
An integrated circuit device including a charge pump circuit comprising:a capacitive element having first and second terminals thereof coupled to an intermediate and capacitor nodes respectively; a first switching device for selectively coupling said intermediate node to a supply voltage line in response to a first clocking signal; a second switching device for selectively coupling said intermediate node to a pumped voltage line in response to a second clocking signal; a first inverter having an input coupled to receive a third clocking signal and an output coupled to a third switching device for selectively coupling said capacitor node to said supply voltage line in response to said third clocking signal; and a second inverter having an input coupled to receive said third clocking signal and an output coupled to a fourth switching device for selectively coupling said capacitor node to a ground voltage line in response to said third clocking signal.
