Abstract

In this work, a Radio Frequency (RF) Energy Harvester comprised of a differential Radio Frequency-to-Direct Current (RF-DC) converter realized in ST130 nm Complementary Metal-Oxide-Semiconductor (CMOS) technology and a customized broadband Printed Circuit Board (PCB) antenna with inductive coupling feeding is presented. Experimental results show that the system can work with different carrier frequencies and thanks to its reconfigurable architecture the proposed converter is able to provide a regulated output voltage of 2 V over a 14 dB of RF input power range. The conversion efficiency of the whole system peaks at 18% under normal outdoor working conditions.
