RF Energy Harvesting Circuit Design Using Broadband Wilkinson Power
Combiner for Low Power Electronics
AbstractRF energy harvesting is a new area of interest as a research topic
during last decade. This paper presents the development of RF energy
harvester circuits using a broadband Wilkinson power combiner technique.
A modified broadband Wilkinson power combiner is introduced and studied.
Authors have proposed a modified voltage multiplier circuit which is the
combination of conventional voltage multiplier circuits like Greinacher
and Villard voltage multipliers. Author has also proposed and studied a
simple MOS based RF energy harvester circuit. The performance of a
Schottky diode based RF energy harvester circuit and a MOS based RF
energy harvesting circuit have been studied. Author also has carried out
Monte Carlo simulation and the simulation results show very small
deviation from its nominal output value. Author has developed a
prototype of a single stage Greinacher voltage multiplier.
