Abstract
The embodiments described herein provide class F amplifiers and methods of operation. So implemented, the class F amplifiers can be used to provide high efficiency amplification for a variety of applications, including radio frequency (RF) applications. In general, the class F amplifiers are implemented with at least one transistor and an output matching network, where the output matching network includes a plurality of resonant circuits configured to facilitate class F amplifier operation. In addition to facilitating class F amplifier operation, the plurality of resonant circuits can also be implemented with other circuit elements to provide output impedance transformation in a way that facilitates efficient amplifier operation.
