摘要

本文介绍了一种高灵敏度射频能量采集器。开发的原型是基于改进的整流器，它利用无源自补偿和偏置技术来提高器件的灵敏度和效率。这些技术包括栅极补偿和整体直流偏置，以降低整流晶体管的阈值电压。该整流器在1 V / 1 μW输出电压和功率下具有84 mV的高灵敏度。

Highly sensitive RF energy harvester using gate and bulk self compensation techniques

This paper presents a highly sensitive RF energy harvester. The developed prototype is based on an improved rectifier, that makes use of passive self compensation and biasing techniques to increase the sensitivity and efficiency of the device. These techniques include gate compensation and bulk DC biasing to lower the rectifier transistors threshold voltage. The rectifier exhibits a very high sensitivity of 84 mV at 1 V / 1 μW output voltage and power.
