A Novel, 2.4 and 5.8GHz Dual-band, 2-Stage RF-DC Charge-pump with Load-tuned Transmission Lines for DC Output Boost (Master's thesis, University of Calgary, Calgary, Canada). Retrieved from https://prism.ucalgary.ca.http://hdl.handle.net/1880/110361A dual-band, RF-DC charge pump without external matching network for wireless energy harvesting in 2.4 and 5.8 GHz bands is proposed. The first novelty here is in the use of optimal length transmission lines on the load side of the 4 half-wave rectifying stages that make up the 2-stage RFCP topology. Simulations and measurements show that doing so boosts the RFCP’s output voltage due to an induced standing wave at each diode’s input and gives the RFCP a 50Ω input impedance without needing an external matching network. The second novelty of this RFCP is the tuned secondary feed that connects the RFCP input to its 2nd stage to give dual-band performance. By tuning this feed such that the RFCP’s 2nd stage and 1st stage impedances in parallel have 0 reactance at 5.8 GHz, return loss resonance in the 5.8 GHz band is achieved in addition to the 2.4 GHz band.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
