本文介绍了第一款支持BLE和Wi-Fi标准的双模唤醒接收器（WuRX）。提出的WuRX通过支持BLE广告信道跳频的频率方案或基于子载波的信道内Wi-Fi跳频方案、支持低功耗RX架构的频率转换方案和实现片上集成的多相图像抑制滤波器，实现了最先进的功率（低至4.4μW）、灵敏度（低至- 92dBm）和抗干扰能力（SIR= - 67dB）。
This paper presents the first dual-mode wake-up receiver (WuRX) that supports both BLE and Wi-Fi standards. The proposed WuRX achieves state-of-the-art power (as low as 4.4μW), sensitivity (as low as −92dBm), and interference resilience (SIR=−67dB) via a frequency plan that supports BLE advertisement channel hopping or a proposed subcarrier-based within-channel Wi-Fi frequency hopping scheme, a frequency conversion plan that enables a low power RX architecture, and an polyphase image rejection filter for full on-chip integration.
