该论文提出了一种5.8GHz能量收集近场无线电芯片,尺寸仅为116μm×116μm,集成了片上线圈天线,无需外部组件。通过创新的功率与信号路径分离设计,解决了微型化无线电中天线同时连接下行链路和电源管理单元的挑战,适用于RFID、可穿戴/植入设备及防伪电子等领域。
would benefit greatly from batteryless compact radios that require no external components. Such a radio could be used for future RFID, wearable/implantable devices, and counter-counterfeit electronics. Previous demonstrations have focused primarily on miniaturizing the radio size [1,2], but relying on off-chip antennas. Two challenges must be overcome to enable sufficiently small radios with on-chip antennas [3]: 1) In most state-of-the-art radios [3-6], the device antenna is connected to both the downlink signal path and the power management unit. Relying on separate signal and power paths incurs an area penalty and degrades antenna matching. In addition, it would be difficult to get a high downlink data-rate since the weak power transfer cannot be disturbed by communication
