A 0.92/5.3nJ/b UWB impulse radio SoC for communication and localization

A UWB radio SoC, including an RF transceiver and a digital PHY, is presented for both communication and ranging. Realized in 0.18 ¿m CMOS, the Tx generates ternary coding and BPSK pulses in the 3-to-5 GHz range, and the Rx achieves a data rate of 0.25 to 20 Mb/s, a noise figure of 7.2 to 8.4 dB, and a sensitivity of -82 to -90 dBm. At 1 Mb/s, only 0.92 nJ/b and 5.3 nJ/b are required for Tx and Rx. Ranging accuracy of <15 cm is realized.
