A 380μW IEEE 802.15.4z IR-UWB pulse-mixing transmitter featuring enable-locking RFDCO with extensive duty-cycling in 22nm FDSOI

The presented IEEE 802.15.4z IR-UWB transmitter is aimed at providing long battery life and compatibility with international standards. Thanks to the optimized pulse shaper and pulse combiner, the sidelobe power is <-29dBc, required for ETSI compliance at 6.5GHz. Extensive duty-cycling in the RF oscillator and the TX enables a low power consumption of 380μW, which is 10× better than state-of-the-art low side-lobe IEEE 802.15.4z transmitters.
