Parasitic circuit compensation method for inverse F class amplifier circuit and inverse F class amplifier circuit

摘要

Provided is an inverse class-F amplification circuit for which parasitic compensation is implemented with respect to the parasitic component of an amplification element. This inverse class-F amplification circuit is equipped with: an amplification unit, which includes a parasitic circuit, and which amplifies an input signal having a prescribed basic frequency and outputs a first signal that includes a basic frequency component, which is a component of the basic frequency, and a high-frequency component, which is a high-frequency component of the basic frequency; a parasitic compensation unit, which resonates with the impedance of the parasitic circuit and thereby is open with respect to a secondary high-frequency component, inputting the first signal and outputting a second signal; and a high-frequency processing circuit, which is open with respect to the secondary high-frequency component, inputting the second signal and outputting a third signal.
