Design and Performance Analysis of 10-Stage Voltage Doublers RF Energy Harvesting Circuit for Wireless Sensor Network
Continuous power supply is very important issue in the purpose of the application of wireless sensor networks. But in the power system of WSN, the battery has a very limited lifetime and is not replaced yet by any other continuous power system. Many researchers are performing several analyses about the energy harvesting circuit of WSNs power system. In this paper, such approach was also performed, with radio frequencies used as input power of energy harvesting circuit for wireless sensor networks. RF energy harvesting technology is not new, but it is able to harvest a minute amount of energy which is not sufficient to continuous power to the node of WSN. In this work, an optimization of the voltage doublers stages in an energy conversion module for Radio Frequency (RF) energy harvesting system at 950 MHz band is presented. Advanced design system (ADS) simulator was used to design a 10-stage voltage multiplier RF energy harvesting circuit, which produces approximately 5 Volt at 0 dBm and maximum 36.489 Voltage. Two 10 stage voltage multipliers were designed and the Agilent diode HSMS-2850 and HSMS-2822 were compared, and finally, it was confirmed that the HSMS-2850 works much better than HSMS-2822 diode. The proposed system can be used to power low power sensors in sensor networks ultimately in place of batteries.
