Abstract:
1. An apparatus comprising: a first transistor configured to provide an output voltage when the first transistor is turned on; a first switching transistor configured to turn the first transistor on; a second switching transistor configured to turn the first transistor off, wherein the first and second switching transistors are configured to be separately switched; a regulated voltage supply coupled to the first switching transistor; a first charge-storage device coupled to the regulated voltage supply; a first path between the first transistor and the first charge storage device; a first switching device along the first path, the first switching device configured to conduct at least a first portion of a charge from the first transistor to the first charge-storage device when the first transistor transitions from on to off; a diode along the first path, the diode configured to prevent a flow of charge along the first path from the first charge-storage device to the first transistor; and a second path between the first charge-storage device and at least one of the first switching transistor and the second switching transistor.
