95µW 802.11g/n compliant fully-integrated wake-up receiver with −72dBm sensitivity in 14nm FinFET CMOS

A 2.4GHz fully-integrated Wi-Fi compliant wake-up receiver in 14nm FinFET technology is presented. The receiver achieves −72dBm sensitivity and +20dBr adjacent channel interference rejection for 62.5kbps at 10−3 BER while consuming 95µW. The OOK-modulated wake-up packet can be transmitted using any legacy OFDM Wi-Fi transmitter.
