Rf Energy Harvesting with Efficient Matching Technique for Low Power Level Application

Development of energy harvesting and wireless power transfer have emerged batteryless and non-contact energy transfer. For optimum power transfer between antenna and the rectifier circuit, impedance of the antenna and rectifier should be match. This paper describes the design and implementation of the 7-stage multiplier in energy harvesting. A Modified dickson configuration is chosen, consists of two HSMS 2850 Schottky diodes and two capacitors for each stage. The aim of this paper is to analyze the performance of the designed rectifier together with matching network. Simulation results show an improvement for the multiplier circuit with a matching network compare to the multiplier alone. Maximum of 60% improvement in rectified output has been achieved at low input power.
