Abstract :
State-space modeling and analysis of a class of switched capacitor RF power amplifiers are introduced resulting in fast and accurate calculation of the output and supply-drawn power as well as of the voltage and current waveforms. Power derivation parameterized on component values and intermediate transformed impedances offers a tool for optimizing the switched capacitor RF power amplifier for maximum output power or maximum Power Added Efficiency. The accuracy of the derived results is verified with SPECTRE (Cadence) simulation.
