چکیده
This paper analyzes some of the losses that occur in non-ideal passive components employed in the ClassE power amplifier. A complete analysis of the Class-E operation in the presence of the switch on-resistance and shunt capacitor ESR has been performed and an analytic dependence of the output efficiency on the parasitic resistances has been derived. New design equations for modified circuit elements are proposed. An overview of other sources of losses in the Class-E circuit is given and the dominant ones are discussed. Keywords— Power amplifier, class E operation, efficiency, passives, parasitics

A Class E Power Amplifier with Low Voltage Stress
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
