Patent ID: 7348847

Claim:
A circuit comprising: a boost capacitor; an amplifier voltage supply output port; a voltage supply input port for receiving a first voltage; an indicator signal input port for receiving an indicator signal; at least a switch responsive to the indicator signal for switching between a first mode of operation and a second other mode of operation, where in the first mode of operation, the at least a switch for charging of the boost capacitor and for providing the first voltage to the amplifier voltage supply output port and in the second mode of operation, the at least a switch for providing a boost voltage at the amplifier voltage supply output port in excess of the first voltage, the boost voltage resulting from a cooperation of the boost capacitor and the first voltage; an amplifying transistor having a base, an emitter and a collector, wherein the amplifying transistor is coupled for receiving a supply voltage from the amplifier voltage supply output port; and an RF signal input port for receiving an RF signal and coupled with the amplifying transistor for amplifying of said received RF signal.
