Voltage Doubler Design for RF Energy Harvesting System

Abstract

This paper deals with the design of Voltage Doubler circuit in an energy transformation network for Radio Frequency (RF) energy generating at 875 MHz The main function of the energy transformation system is to transform the radio frequency signals into direct current at a desired frequency band. Then this will be provided to the circuits or components which wields low power. A 5 stage voltage multiplier network based on Schottky diode is designed and simulated. It yields a DC output potential in measurement. The main advantage is that it does not require DC boosters. The voltage harnessed can be given to power sensors and instead of batteries these can be wielded which is cost effective.
