Abstract : This paper presents an analysis simulation of the performance on the MOSFET rectifier circuit designed to operate at ultra-low power levels by utilizing of RF energy harvesting source for a wireless microsensor network applications. Research on energy harvesting proposes that micro sensors could utilize the harvested energy from the surroundings. This research aims to propose an architecture of ultra-low power operation and energy efficiency enhancement in RF energy harvester from RF energy sources captured by surface-micro machined patch antenna. The MOSFET rectifying circuit is simulated and analyzed using PSPICE software. Three different transistors are studied for rectifying an AC signal at 5 GHz operating frequency. A comparison between CMOS technology and normal transistor conditions in which identifying one transistor in 0.13-μm CMOS technology implementation and two different commercial Philips transistors, respectively, has been investigated. The input power levels of focus are ranging from -30 to 10 dBm. The simulated results indicate the maximum DC output voltage of 2.15 V from low input power source of -20 dBm at high resistance load of 1 MΩ on the transistor-based implementation. Characterization of efficiency plots reveals approximately 99.47% improvement compared to other commercial transistor-based with commercial capacitance-based system. Thus, it is demonstrated that the proposed architectural design deals a promising solution for an efficient functionality at ultra-low power of RF energy harvesting system.
