Abstract
- This paper presents a novel design procedure for the class-EM amplifier. The numerical design procedure is applied to the design of the class-EM amplifier, which achieves simple and accurate designs for high-order circuits. As a result, no tuning process is necessary in the circuit implementations. In this paper, two types of auxiliary circuits are considered, namely, the zero-voltage switching class-E amplifier and the zero-voltage switching class-E frequency doubler. The class-E auxiliary amplifier has a lower driving power and a higher output power capability than the class-E auxiliary frequency doubler. On the other hand, the class-E auxiliary frequency doubler has lower number of the non-zero-current switchings than the class-E auxiliary amplifier and no on-interval of the antiparallel diode of the MOSFET. The laboratory experimental results agreed quantitatively with the numerical predictions, which validate the effectiveness of the proposed design procedure. [ABSTRACT FROM AUTHOR]
