Abstract
A power amplifier system is provided that includes a power amplifier configured to receive an RF input. A DC-DC converter is coupled to the power amplifier. Clocking circuits drive the DC-DC converter. The clocking circuits use the RF input to generate a clock. The clock acts with the DC-DC converter to provide an output voltage used in the power amplifier.
