Abstract

In this paper, a comparison between different types of rectifier circuits for RF energy harvesting is conducted. Six types of rectifier circuits consisting of half-wave, full-wave, voltage doubler, Villard charge pump, Graetz charge pump, and Dickson charge pump are designed and simulated. These various types of rectifier circuits are designed for different resistance loads, HSMS282X diodes and standard substrate materials that represents the dielectric constant. Firstly, the rectifiers are firstly designed on an FR-4 substrate with a thickness of 1.6 mm and a dielectric constant of 4.3 using a single-stage LC-match method at 2.4 GHz. The studied range of the input power was from 0 dBm to 30 dBm, the resistance load is 3 kΩ, and the HSMS2820 diode is used. The highest recorded output voltage for the Graetz charge pump was around 27 V, while the highest recorded efficiency for the Graetz charge pump was also 27%. Advanced Design System (ADS) software is used to simulate the rectifier circuits..
