Abstract:
A system for pre-charging a current minor includes a controller configured to provide a first current and an additional current to a current minor to rapidly charge a capacitance associated with the current minor based on a reference voltage or control signals. A power amplifier module includes at least one current minor and a controller. A capacitor is coupled to the current minor. The controller provides a bias current in an amount proportional to an input to a voltage-to-current converter. The controller receives a control signal that directs the controller to apply one of a pre-charge voltage and a nominal voltage to the voltage-to-current converter.
