Abstract
In this work we present an IC architecture of RF energy harvesting for wireless sensors networks. By analyzing a probabilistic approach used for modeling the possible amount of Global System for Mobile Communication (GSM) energy that could be harvested, an IC system with a 0.18μm CMOS SMIC technology has been designed and optimized at 90 and 900 MHz. so to take advantage of the GSM and FM radio radiated energy. Simulation results have confirmed that the integrated system handles an incoming power typically ranging from -25 dBm to 5 dBm by rectifying the variable input signals into a DC voltage source. The overall RF to DC efficiency is about 45% at 90MHz and 55% at 900MHz.Pubblicazioni consigliate
