Abstract :
Analytical theory and simulation-based analysis for optimizing sensitivity of RF energy harvester are discussed. A target harvester is a widely-used MOSFET Dickson charge-pump harvester from a small-signal RF power with a voltage booster at the front end. Charging time is also analyzed. Derived expressions show good match with simulation results. The results provide an insight for design optimization based on circuit and device parameters.
