Abstract(in English) | In an RF energy-harvesting utilizing environmental electromagnetic waves, a high-efficiency rectifier is required to convert the ultra-low power environmental electromagnetic waves into DC power. In this paper, a circuit configuration of a self-switching-type transistor rectifier has been proposed by using the anti-resonance between the feedback capacitance in the transistor and the external inductor, in order to increase both of the gate switching voltage and drain voltage swing. The operation was successfully analyzed based on a small-signal equivalent circuit approximation. Then, for a realization of the ultra-low power transistor rectifier, a low-threshold enhancement-mode GaAs HEMT with strong nonlinearity was used. A fabricated enhancement-mode GaAs HEMT rectifier exhibited an RF-to-DC conversion efficiency of 23.2% and DC output voltage of 21 mV for -30 dBm input power at 2.4 GHz band |
