本文介绍了一款高度集成、电源、温度和干扰鲁棒的事件驱动唤醒接收器（WuRx），采用定制设计的天线，在4.9 GHz时灵敏度可达-dBm，在5.3 GHz时与50个源匹配时灵敏度可达-dBm，室温下功耗为184 nW。该芯片采用65 nm CMOS LP技术制造，采用单电源供电。提出了一种新型的缝隙天线，直接与芯片的输入端进行共轭匹配，消除了有耗阻抗匹配网络。集成的基准电压源和调节器使接收器能够在至70的宽温度范围和1.2至1.5 V的电源范围内工作。集成的比例积分微分（PID）控制模块使WuRx能够自动适应周围环境中存在的不同温度和干扰信号。
This article presents a highly integrated, supply, temperature, and interference-robust, event-driven wake-up receiver (WuRx) achieving-dBm sensitivity using a custom-designed antenna at 4.9 GHz or-dBm sensitivity when matched to a 50-source at 5.3 GHz, consuming 184 nW at room temperature. The chip is fabricated in 65-nm CMOS LP technology and powered by a single supply. A novel slot antenna is proposed to directly conjugate match to the input of the chip and eliminate lossy impedance matching networks. The integrated references and regulation enable the receiver to operate for a wide range of temperatures fromto 70and a supply range from 1.2 to 1.5 V. The integrated proportional–integral–derivative (PID) control module allows the WuRx to automatically adapt for different temperatures and interference signals present in the ambient environment.
