Hybrid Voltage Compensation Topology based RF Rectifier for RF Energy Harvesting

In our contemporary context, the development of energy harvesting topology has drawn considerable interest. Due to its accessibility, RF energy harvesting is expected to have a promising future in producing a little amount of electrical power to operate a variety of low power electronics equipment. In order to transform an RF signal into usable electrical power, rectifier circuits with various compensation topologies are presented by different researchers. In this context, hybrid i.e. combination of Self Voltage Compensation and Internal Voltage Compensation is proposed to attain high efficacy than other existing topologies. The circuits are designed and simulated in Cadence Virtuoso Tool with 45nm CMOS technology. It is noted that the output voltage of 2.1V at 500MHz frequency.
