Abstract
Using IR-UWB for accurate battery-powered localization requires low energy consumption and high interference resilience. The presented IR-UWB 802.15.4z transceiver features low power consumption thanks to its inverter-based RX architecture and polar TX. The two-stage distributed PLL enables simultaneous multi-channel reception, reducing the energy consumption and measurement time of localization. It consumes 8.9mW in TX mode and 21.5mW/ch. in RX mode while achieving -33dBm OOB blocker tolerance.
