Abstract
A bias voltage generator circuit may include a mode control circuit, a clock generator circuit coupled with the mode control unit and configured to generate a plurality of clock signals, and a charge pump circuit configured to receive the clock signals. The charge pump circuit may be coupled with the mode control circuit and operable to output selectable output voltages according to input from the mode control circuit. The output selectable voltages may depend upon the clock signals.
