Derivation of the Resonance Mechanism for Wireless Power Transfer Using Class-E Amplifier
In this study, we investigated the resonance mechanism of 6.78 MHz resonant wireless power transfer (WPT) systems. The depletion mode of a gallium nitride high-electron-mobility transistor (GaN HEMT) was used to switch the states in a class-E amplifier ...

High-Frequency Power Amplitude Modulators with Class-E Tuned Amplifiers
A high-frequency power amplifier used in a drain amplitude modulator must have linear dependence of output HF voltage Vo versus its supply voltage VDD. This condition essential for obtaining low-level envelope distortions is met by a theoretical class-E
