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 kΩ. Furthermore, a peak PCE of 54.85% and 47.87% was achieved for R_L = 100 kΩ and R_L = 150 kΩ, respectively. The sensitivity for an output voltage of 1 V with R_L = 100 kΩ is -20.6 dBm.

本文介绍了一种用于专用远场RF能量收集系统的双输入扩展动态范围高PCE整流器。将两个相同的输入RF能量供应源应用到两个单独的整流器中。选择具有最高PCE的整流器可将直流电输送到单负载元件。逻辑控制电路从整流后的直流电压感测P _in，并通过生成两个控制电压在P _in上获得高PCE来在整流器之间切换。在65nm CMOS工艺中进行仿真，提出的系统针对R _L  = 100kΩ的输出负载实现了26 dB的扩展DR 。此外，对于R _L  = 100kΩ和R，达到了峰值PCE分别为54.85％和47.87％。_L 分别为150kΩ。R _L  = 100kΩ的1 V输出电压的灵敏度为-20.6 dBm。
