Abstract
Within an amplifier circuit having an amplifying transistor, a boost voltage is presented at a port of the transistor. The amplifying transistor has a base, an emitter and a collector or a gate, a source, and a drain. A capacitor is provided in electrical communication with the transistor. A voltage source is provided for providing one of the collector and the source with a first voltage and for in a first mode of operation charging the first capacitor. Also within the circuit is a switch for switching between the first mode of operation and a second other mode of operation wherein the first capacitor and the voltage source cooperate to provide a voltage at one of the collector and the source in excess of the first voltage.
