Computer-Aided Design of Switchmode Power Amplifiers

Introduction

Nonlinear circuit simulation in the frequency and time domains is a very important tool for analysis, design, and optimization of high-efficiency switchmode power amplifiers of Classes D, DE, and E. The advantages are significantly reduced development time and final product cost, better understanding of the circuit behavior, and faster obtaining of the optimum design. It is especially important at very high frequencies, including microwaves, and for MMIC development, where the transistor and circuit parasitics can significantly affect the overall power-amplifier performance. Therefore, it is very important to incorporate into the simulator as accurate a transistor ...
