An ultra-low-power GaAs pHEMT rectifier has been developed at 900 MHz band for IoT sensor network systems based on an energy harvesting technique. To obtain a high-efficiency characteristic, a nonlinear operation has to be imposed for the rectifier even if at the ultra-low input power. By increasing a drain termination impedance and DC load resistance, a distorted voltage swing at a transistor to obtain an sufficient rectified DC output is achieved at the ultra-low input power. A fabricated rectifier exhibited an RF-to-DC conversion efficiency of more than 10% at an input power of more than -17 dBm, and about 1% was obtained at -30 dBm input with a DC output voltage of 9.1 mV. |
