Abstract:
A circuit including a carrier amplifier having an input, an output, a first transistor coupled to a first power supply voltage terminal for receiving a modulated power supply voltage, and a second transistor coupled to a second power supply voltage terminal for receiving a fixed power supply voltage is provided. The circuit further includes a peaking amplifier having an input coupled to the input of the carrier amplifier and an output coupled to the output of the carrier amplifier.
