ABSTRACT:
A voltage boosting circuit which derives an output voltage than is substantially twice the magnitude of a supply voltage applied thereto. The voltage boosting circuit consists of complementary acting boost circuits each having a pair of switches (42A, 52A; 42B, 52B) connected between an input of the voltage boosting circuit, at which is applied the supply voltage, and an output at which the output voltage is produced. Boost capacitors (48A, 48B) are connected between the respective switches of the complementary boost circuits and the switches of the these circuits are opened and closed out of phase with respect to each other in response to clocking signals being applied thereto such that a boosted output voltage is produced during each half cycle of the clocking signals.
