This paper presents a dual-input extended-dynamic-range, high-PCE rectifier for dedicated far-field RF energy harvesting systems. Two identical input RF energy supply source are applied into two individual rectifier. The rectifier with the highest PCE is selected to deliver dc power to a single-load element. A logic control circuit senses P-in from the rectified dc voltage and toggles between the rectifiers by generating two control voltage to attain high-PCE across P-in. Simulated in a 65nm CMOS process, the proposed system achieves an extended DR of 26 dB for an output load, R-L = 100 k omega. Furthermore, a peak PCE of 54.85% and 47.87% was achieved for R-L = 100 k omega and R-L = 150 k omega, respectively. The sensitivity for an output voltage of 1 V with R-L = 100 k omega is -20.6 dBm.
