Abstract: A rectifier circuit is studied to harvest the ambient RF power at 2.45 GHz frequency. The circuit comprises a dual branch of Greinacher voltage doubler. This study addresses the problem of saturation due to diode threshold voltage. In fact, as the number of diodes used increases the reverse effect can be seen on the output voltage after a certain number of diodes. The results of the simulation of our rectifier show an output voltage of 2V at 2.45 GHz with 0 dBm input power.
