A contactless scribe-line channel-leakage monitor with relaxed alignment requirement is described. It comprises photovoltaic converters for powering from indoor illumination, a visible light communication downlink for selecting one among multiple monitors, and an ultra-wideband impulse-radio uplink for transmitting the measured leakage data in the form of impulse repetition frequency. Readout is accomplished with an external loop antenna loosely aligned to the scribe-line transmitter antenna. The proposed monitor was implemented in 0.18-μm CMOS with a footprint 4960 μm \(\times \) 160 μm including the transmitter antenna. It deploys a novel leakage sensor of ring-oscillator topology. All circuit blocks, except for the transmitter, are power-supplied directly by photovoltaic converters without regulation, and consume 64 nW. Transmitter is powered by an integrated storage capacitor charged to 1.8 V by a photovoltaic-powered voltage booster.

描述了一种具有宽松的对准要求的非接触式划线道漏电监测器。它包括用于从室内照明供电的光伏转换器，用于在多个监视器中选择一个的可见光通信下行链路，以及用于以脉冲重复频率的形式传输所测量的泄漏数据的超宽带脉冲无线电上行链路。读出是通过与划线发射器天线松散对准的外部环形天线完成的。拟议的监控器采用0.18-μmCMOS实施，占地4960μm \（\ times \）包括发射器天线在内为160μm。它部署了一种新型的环形振荡器拓扑泄漏传感器。除发射器外，所有电路模块均由光伏转换器直接供电，无需调节，功耗为64 nW。变送器由集成的存储电容器供电，该电容器由光伏电源升压器充电至1.8V。
