Abstract
An apparatus includes a charge pump array including multiple charge pump cells. The charge pump array is configurable into a first arrangement of the charge pump cells coupled in series or a second arrangement of the charge pump cells coupled in parallel. The apparatus can include reconfiguration circuitry configured to select the first arrangement of the charge pump cells or the second arrangement of the charge pump cells. The charge pump array is configured to alter a voltage level of a signal based, at least in part, on the selected arrangement of the charge pump cells.
