The method of selection class E/F₂ inverter parameters and their optimization

This paper presents a new family of harmonic tunings with the promise to achieve the performance benefits of class F by reducing the peak voltage and RMS current of class E designs. These class E/F amplifiers have class-E features such as incorporation of the transistor parasitic capacitance into the circuit, exact truly-switching time-domain solutions and allowance for Zero Voltage Switching (ZVS) operation. Additionally, some number of harmonics may be tuned in the fashion of inverse class F in order to achieve more desirable voltage and current waveforms for improved performance.
