本文提出了一种具有自动偏移补偿功能的唤醒无线电接收机，实现了-76dBm的灵敏度和7.4nW的超低功耗，解决了事件驱动传感器节点在休眠状态下低功耗唤醒的难题。
Stephen Pancrazio, N. Scott Barker, Benton H. Calhoun, Steven M. Bowers University of Virginia, Charlottesville, VA Event-driven sensor nodes have applications in agriculture, infrastructure, and perimeter monitoring and are characterized by spending the vast majority of their time in an asleep-yet-alert state. In this state, the node must wake to incoming RF wakeup commands from an antenna with minimal dc power, as the total percentage of power in sleep mode dominates if wakeup events are sufficiently infrequent. The RF wakeup receiver (WuRX) is one critical block of the node’s asleep-yet-alert state. It must maximize sensitivity with power consumptions of 10nW or less to maximize battery lifetime or even enable battery-less systems that persist on energy harvesting [1-3]. These WuRXs must reliably detect wakeup signals as well as reject false wakeups caused by external interferer signals or noise. Otherwise,
