Abstract
Certain aspects of the present disclosure are directed to an amplifier. The amplifier may include a transistor coupled to an output of the amplifier, and a resonator coupled between the output of the amplifier and a reference potential node, a resonant frequency of the resonator being set to be at a subharmonic of a fundamental frequency of the amplifier, and an impedance of the resonator being greater than a load impedance of the amplifier at the fundamental frequency of the amplifier.
