A 0.75-to-1GHz Passive Wideband Noise-Cancelling 171µW Wake-Up RX and 440µW Primary RX FE with -86dBm/10kb/s Sensitivity, 35dB SIR and 3.8dB RX NF

📋 论文概要

本文提出了一种工作在0.75-1GHz的被动宽带噪声消除唤醒接收器和主接收器前端，分别仅消耗171µW和440µW，并实现了-86dBm@10kb/s的灵敏度。通过共享电路和被动噪声消除技术，解决了IoT收发器中低功耗与高性能接收的矛盾。

💡 主要创新点

• 提出被动宽带噪声消除结构，实现低功耗下良好的噪声性能
• 双模接收器（唤醒和主接收）共享关键电路，降低总功耗和面积
• 在极低功耗（171µW/440µW）下达到-86dBm灵敏度，适合IoT应用
