摘要：
This letter proposes a new rectifier circuit design operating with a reasonable efficiency for RF energy harvesting at 2.45GHz. The circuit is composed of an impedance matching network, a voltage-doubler for converting RF power into DC voltage and a low-pass filter. Our device outperforms other published counterparts with a maximum conversion efficiency up to 73.4% when the input power is 4.5dBm. The simulation is implemented and a prototype is fabricated. The measured maximum RF-DC conversion efficiency of the prototype is about 52% at 4.5dBm input power.
