Abstract:
An apparatus, comprising:a reconfigurable charge pump circuit including a first section and a second section, and having a first configuration in which the first section and the second section are coupled in parallel to form parallel charge pump circuits, and having a second configuration in which the first section and the second section are coupled serially to form a single charge pump circuit; and a first output circuit having an input coupled to an output of the first section, and a second output circuit having an input coupled to an output of the second section, the second output circuit further having an output coupled to an output of the first output circuit; wherein the first output circuit is operable as a voltage-smoothing output device for the first section when the reconfigurable charge pump circuit is in the first configuration and is operable as a diode circuit when the reconfigurable charge pump circuit is in the second configuration.
