Abstract
The present invention provides a method, apparatus, and system for rapid transition of a charge pump circuit from a low power state to a high power state. The charge pump circuit has at least one pump stage. The at least one pump stage includes at least a first capacitor coupled to a gate of a first switching transistor forming a boot node and at least a second capacitor coupled to an output node of the at least one pump stage. It is determined whether the charge pump circuit is in the low power state or the high power state. If the charge pump circuit is in the low power state, a first predetermined voltage and a second predetermined voltage that are different than the ground voltage level are applied to the boot node and the output node, respectively. If the charge pump circuit is in the high power state, the first predetermined voltage and the second predetermined voltage are removed from the boot node and the output node, respectively.
