315MHz OOK transceiver with 38-µW receiver and 36-µW transmitter in 40-nm CMOS

A 1-Mbps, 315MHz OOK transceiver in 40-nm CMOS for body area networks is developed. Both a 38-pJ/bit carrier-frequency-free intermittent sampling receiver with -55dBm sensitivity and a 36-pJ/bit transmitter applied dual supply voltage scheme with -20dBm output power achieve the lowest energy in the published transceivers for wireless sensor networks.
