Özet

The different rectifier circuit structures are used in the in RF energy harvesting systems. The main structures used to obtain DC power from RF signals are half-wave serial rectifier, half-wave parallel rectifier, differential rectifier, Villard voltage doubler rectifier, Dickson voltage doubler rectifier and the Greinacher charge pump. In this paper, operation principles of these circuit topologies are mentioned and the efficiency values of these structures at different input power levels and at the different frequency values are examined.
