The design of a carrier-less RF-correlation-based IR-UWB TRX front-end in 130 nm CMOS is presented. Timing synchronization and coherent demodulation are implemented directly in the RF domain, enabling energy-efficient wireless communication at Gb/s data rates. A 25 ps timing resolution is achieved by a two-step synchronizer. Occupying 6.4 mm2 chip area, the TRX achieves a maximum data rate of 2 Gbps and an RX sensitivity of -64 dBm with a BER of 10-5, while requiring only 51.5 pJ/pulse in the TX mode and 72.9 pJ/pulse in the RX mode.
