Patent ID: 8384467

Claim:
An apparatus comprising: a charge pump array including multiple charge pump cells; control circuitry configured to generate control signals based on received configuration signaling, wherein the configuration signaling is configured to identify an arrangement of the charge pump cells that is based on a voltage level of a signal to be boosted by the charge pump array, and wherein the control circuitry comprises: a down pump configured to reduce a voltage level of a signal received from the charge pump array by a preset voltage magnitude, a level shifter configured to select the signal with the reduced voltage level as at least a portion of the control signals; and reconfiguration circuitry configured to select a first arrangement of the charge pump cells coupled in series or a second arrangement of the charge pump cells coupled in parallel in response to the control signals, wherein the charge pump array is configured to alter the voltage level of the signal based, at least in part, on the selected arrangement of the charge pump cells.
