This article presents an 802.11ba-based wake-up radio (WUR) receiver that is fully integrated within an 802.11a/b/g/n/ac Wi-Fi transceiver. Low-cost integration is achieved with the WUR only occupying 0.13 mm2while not adding any additional overhead to the Wi-Fi platform. The WUR consumes 667 μW from 1.1-V Wi-Fi system supply. When measured from internal 0.6and 0.9-V supplies, the receiver consumes 495 μW. The receiver has a measured sensitivity of -92.6 dBm and can tolerate -40.5-dBm Wi-Fi adjacent channel blocker with 3-dB receiver de-sensitization. The WUR and Wi-Fi system co-operation is also demonstrated. The WUR receiver can operate when the Wi-Fi system is in sleep mode and can turn on Wi-Fi radio upon receiving 802.11ba-based wake-up packet.
