摘要

本文介绍了一种无线接收器系统,该系统可以从带外射频阻挡器中获取能量,从而实现可持续运行并延长物联网应用的电池寿命。所提出的射频接收器系统架构工作在900 MHz频段,采用CMOS 180 nm制造,可以在不可避免的高带外阻挡物(≈0 dBm)存在下工作,但功耗为534 μW。此外,46%的直流功率是通过射频能量收集技术从现有的阻滞剂中提取的。

A 540 µW RF wireless receiver assisted by RF blocker energy harvesting for IoT applications with +18 dBm OB-IIP3
This paper introduces a wireless receiver system that harvests energy from the out-of-band RF blockers which enables sustainable operation and extends battery life for IoT applications. Operating at 900 MHz band and fabricated in CMOS 180 nm, the proposed RF receiver system architecture can operate at the presence of unavoidable high out-of-band blockers (≈0 dBm) yet consumes 534 μW. Moreover, 46% of this dc power is extracted from existing blockers via RF energy harvesting techniques.
