Abstract :
In this paper, a wide power range RF energy harvesting circuit is presented. The proposed idea is based on optimizing the performance of the contained Schottky diodes, while considering their built-in potential, breakdown voltage and variable impedance properties. The carried out analysis revealed a greater than 50% RF-to-DC conversion efficiency over a wide range of input power extending from -10 to 8.5 dBm. The proposed design is suitable for ambient RF energy harvesting applications, where the received RF signals undergo an abrupt variation of power level.
