SleepTalker: A 28nm FDSOI ULV 802.15.4a IR-UWB transmitter SoC achieving 14pJ/bit at 27Mb/s with adaptive-FBB-based channel selection and programmable pulse shape

We propose a UWB transmitter (TX) SoC designed for ultra-low voltage (ULV) in 28nm FDSOI CMOS. Operated at 0.55V, it achieves a record energy efficiency of 14pJ/bit with embedded power management (PM), highly duty cycled digital baseband, programmable pulse shaping and wide-range on-chip adaptive forward back biasing (FBB) for V T reduction, PVT compensation and tuning of both the carrier frequency (CF) and the output power.
