Impulseradio ultra-wideband (IR-UWB) is a promising solution for accurate ranging due to its wideband operation. The recently released IEEE 802.15.4z standard [1] improves upon the security of ranging and mandates a coherent operation with higher mean pulserepetition frequencies (mPRF), in comparison to the legacy standard IEEE 802.15.4a. The next generation IR-UWB devices demand ultra-low-power operation while meeting the strict spectrum regulations to operate worldwide in C and X bands (4 to 10GHz). The prior-art coherent IR-UWB transmitters either consume very high power [2] or result
