Abstract :
In this paper, a novel rectifier using a single diode with a series inductor is proposed. The introduced series inductor has effects on the voltage and the current of the diode. It aids to suppress the harmonic frequencies and improve the RF-to-DC Eff. consequently. Both circuit simulation and experimental results show the dynamic range of the load widens and the RF-to-DC Eff. increases, compared with a conventional single diode rectifier. The rectifier using a diode with a series inductor could enhance the impedance matching and improve the rectifying performance, while the design procedure remains unchanged and there is no extra complexity in the rectifier.
