A novel high-efficiency class-F voltage doubler rectifier for RF energy harvesting
In this letter, a high-efficiency 2.45 GHz class-F voltage doubler rectifier is proposed for radio frequency energy harvesting (RFEH). In the proposed topology, two harmonic termination circuits are employed to shape the current waveform to half sine wave and voltage waveform to square wave by yielding short termination at even harmonics and open termination at odd harmonics. Compared with previous class-F voltage doubler rectifiers, the proposed rectifier achieves a higher RF-DC power conversion efficiency (PCE). To validate the proposed approach, a 2.45 GHz voltage doubler rectifier has been designed and implemented. The measurement results show that the peak RF-DC PCE is 76% with a 15.6 dBm input power range. In addition, the measured PCE is higher than 50% over the input power range from 2 to 18 dBm.
