Abstract

This paper presents an optimization of the rectifier module for Radio Frequency (RF) energy harvesting system at 915 MHz band. This module converts the RF signal into direct-current voltage at the given frequency band to power ultra-low power bio-medical sensor. A transient analysis on various types of rectifier circuit is carried out to investigate their efficiency and sensitivity. To improve the power conversion efficiency, the voltage boosting network increases the voltage at the input of the full wave rectifier. By assuming the system is at resonance condition, the optimum parameters including the value of capacitance, inductance and load value are calculated. Simulation results show that passive component based circuit can significantly increase the RF input voltage and broaden the input range of the rectifier. The modified circuit enhances output voltage approximately 400 mV higher than output voltage from existing full wave rectifier at same level of input. This will help to increase the input range to be converted to dc output.

基于升压网络和生物医学器件体调制技术的微能量采集器RF- DC变换器优化

本文对915mhz频段射频能量采集系统的整流模块进行了优化设计。该模块将射频信号转换为给定频段的直流电压，为超低功耗生物医学传感器供电。对各种类型的整流电路进行了暂态分析，考察了它们的效率和灵敏度。为了提高功率转换效率，升压网络提高了全波整流器输入端的电压。假设系统处于谐振状态，计算出电容值、电感值和负载值等最优参数。仿真结果表明，基于无源元件的电路可以显著提高射频输入电压，拓宽整流器的输入范围。在相同输入电平下，改进电路的输出电压比现有全波整流器的输出电压高约400mv。这将有助于增加要转换为直流输出的输入范围。
