Abstract

See full text

A power amplifier includes first and second amplification stages. The first amplification stage is configured to amplify a radio frequency (RF) input signal. The second amplification stage includes at least one transistor configured to amplify an output of the first amplification stage, the second amplification stage being configured to have a capacitance between a gate of the at least one transistor and a first power supply voltage. The capacitance automatically varies with amplitude of the output of the first amplification stage.
