Abstract
This article presents a dual-mode wake-up
receiver (WuRX) compatible with both Bluetooth-Low-Energy
(BLE) and Wi-Fi transmitters. The proposed WuRX achieves the
state-of-the-art power (as low as 4.4 µW through a latency-power
duty-cycled tradeoff), sensitivity (as low as −92 dBm), and inter-
ference resilience (signal-to-interference ratio (SIR) =− 67 dB)
via a carefully architected frequency plan that supports BLE
advertisement channel hopping or a proposed subcarrier-based
within-channel Wi-Fi
