摘要

本文概述了目前超低功耗无源超高频RFID标签的设计技术。讨论了专用传感器数据采集方法以及通用传感器接口及其构建模块。模数转换器工作在小于100 fJ/转换步长范围内，可作为通用接口的数据转换器。在单个电路上进行了示例计算和仿真，以证明在1 V电源电压下只有几μ A的UHF RFID条件下的可操作性。

Ultra low-power techniques for sensor-enhanced RFID tags

This paper gives an overview on current design techniques for ultra low-power applications in passive UHF RFID tags. Specialized sensor data acquisition methods are discussed as well as generic sensor interfaces and their building blocks. Analog to digital converters working in ranges of less than 100 fJ/conversion-step are presented which can be applied as data converters for generic interfaces. Example calculations and simulations on single circuits are made to prove operability at UHF RFID conditions of only several µA available at 1 V supply voltage.
