摘要

Detailed state-space modeling and analysis of a class of RF switched-capacitor power amplifiers achieving high efficiency, output power, and linearity are presented. Time-domain voltage and current waveforms are analytically obtained via the steady-state solution of the amplifier’s model equations. The output power of the fundamental and that of the harmonics, as well as the drain efficiency of th...
