This paper presents the design of a novel differential voltage octuple rectifier for wireless RF energy harvesting. Two rectifiers with common matching (CM) and two‐branch matching (TBM) are presented for the CDMA850/GSM900 bands operation. Measured maximum efficiencies of CM and TBM rectifiers reach 66.5% and 70.6%, respectively. The results also show that both matching network‐type rectifiers can produce higher output voltage. It is demonstrated that the designed rectifier‐antenna structure powers up a battery‐less LCD sensor by harvesting RF signal of a dialing cell phone. The proposed rectifier topology and matching mechanisms can be used for various energy harvesting applications, especially for those requiring high supply voltage.
