RF energy harvesting holds a promisinge future for generating a small amount of electrical power to drive partial circuits in wirelessly communicating electronics devices. This paper presents an energy harvesting system based on LTC3108, which can effectively collect the surrounding WiFi energy. Two rectifier circuit, the Villard cascade circuit and the Greinacher circuit, were analyzed. In this paper, the Schottky diode HSMS-2852 was used to form the RF-DC rectifier circuit When the input voltage of the LTC3108 power management circuit is higher than 30mV, the output of the power management circuit can achieve at 3.29V.
