摘要

提出了一种0.13 μ m CMOS时钟采集接收器，该接收器提取嵌入GSM标准的21Hz时钟，用于无线传感器网络的唤醒。在主动模式下，接收器达到−87dBm灵敏度，输出抖动为57µs，功耗为126µW。该接收器针对重占空比进行了优化，睡眠模式功耗仅为81pW。

A 1900MHz-band GSM-based clock-harvesting receiver with −87dBm sensitivity

A 0.13µm CMOS clock-harvesting receiver is presented which extracts a 21Hz clock embedded within the GSM standard for the wake-up of a wireless sensor network. In active mode, the receiver achieves −87dBm sensitivity with 57µs of jitter at the output while consuming 126µW. The receiver is optimized for heavy duty-cycling with a sleep-mode power consumption of only 81pW.
