Various embodiments of the present technology may comprise methods and apparatus for controlling a bias voltage. Methods and apparatus for controlling a bias voltage to an electrical device according to various aspects of the present invention may operate in conjunction with a charge pump and a voltage regulator. A pulse generator may be employed to vary the output voltage of the voltage regulator, which in turn, varies the output voltage (bias voltage) generated by the charge pump. The pulse generator may be activated at the start-up of the electrical device.
