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 the switched-capacitor power amplifier (SCPA) are derived. The state-space model is implemented in MATLAB and all theoretical results are compared to Cadence Spectre simulation of the SCPA and are found to be in good agreement.
