Original Abstract Submitted
A Doherty amplifier circuit includes a carrier amplifier including one or more amplifiers, and a peaking amplifier including one or more amplifiers. At least one of the amplifiers includes a transistor and a feedback circuit. The transistor receives, at its base or gate, a radio frequency signal and a bias voltage or current which changes, and outputs an amplified radio frequency signal from its collector or drain. The feedback circuit provides, to the base or gate or the emitter or source of the transistor, a voltage or a current based on the amplified radio frequency signal.
