本文提出了一种新型的唤醒接收器，即时钟采集接收器，它提取嵌入GSM标准的21hz时钟用于无线传感器网络的唤醒。该接收器采用0.13 μm CMOS制作，从1900-MHz GSM频段获取21 Hz时钟。它被设计用于重占空比操作，以减少网络同步所需的能量。在主动模式下，接收机的灵敏度为-87 dBm，抖动为57 μs，功耗为126 μW。休眠模式下，功耗为81pw。在实验室中进行的实验用真实的本地GSM蜂窝信号验证了接收器的功能。
This paper presents a new type of wake-up receiver, called a clock-harvesting receiver, which extracts a 21 Hz clock embedded within the GSM standard for the wake-up of a wireless sensor network. The receiver was fabricated in 0.13 μm CMOS and harvests a 21 Hz clock from the 1900-MHz GSM band. It was designed for heavily duty-cycled operation to reduce the energy required for synchronization of a network. In active mode, the receiver achieves a sensitivity of -87 dBm with 57 μs of jitter while consuming 126 μW. In sleep mode, the power consumption is 81 pW. Experiments conducted in the lab verify the functionality of the receiver with a real local GSM cellular signal.
