Development of micro energy harvest circuit using RF signal

This paper presents the design of the micro energy harvesting circuit (MEH) for sensor network systems by using radio wireless waves for wireless telecommunication system. A series L and C resonance circuit is connected in front of the RF-to-DC converting circuit in our proposed circuit in order to enhance the radio frequency (RF) signal. RF-to-DC converting circuit is based on the Dickson voltage multiplier and designed the cascode and cascade connection to obtain the high DC output voltage. Surface mount type devices such as diode, capacitor etc. are placed on the differential strip line. In the simulation, cascade structure has more than 2V DC output from 900MHz to 2.4GHz.
