An 802.11ba 495μW -92.6dBm-Sensitivity Blocker-Tolerant Wake-up Radio Receiver Fully Integrated with Wi-Fi Transceiver

An 802.11ba-based wake-up radio (WUR) receiver is presented. The WUR receiver prototype is integrated within an 802.11a/b/g/n/ac Wi-Fi transceiver, occupying 0.05mm2 for RF/analog frontend and 0.08mm2 for digital baseband. The WUR receiver consumes 495µW standalone and consumes 667µW from Wi-Fi system supply. The receiver has a measured sensitivity of -92.6dBm and can tolerate -40.5dBm Wi-Fi adjacent channel blocker with 3dB receiver de-sensitization. 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 over the air.
