| Abstract(in English) | Low power rectifier for RF energy harvester based on a new operation principle is presented. The single-diode rectifier employs an external series inductor resonating with the diode parasitic capacitances. The resonance leads to almost perfect input impedance matching to the RF source (antenna) over wide dynamic input power range, as well as enhanced diode-sensitivity to the weak environmental RF signal. The unique operation mechanism of the rectifier is explained based on a physical circuit model which is verified by a simulation study. Prototype rectifiers for 700-MHz bands were designed and fabricated using commercial discrete diodes, demonstrating 38% RF-DC conversion efficiency at RF input power of -20 dBm. |
