Abstract :
This paper describes the integration in a 0.13 μm CMOS of an Ultra Wide Band (UWB) receiver for communication and localization. It operates in the whole 3.2-to-4.7 GHz band of the IEEE.802.15.4a regulation mask. The proposed double quadrature coherent architecture allows exploiting high resolution capability of short pulses in the time domain, with a low sampling clock at 50 MHz. Architecture offers high flexibility to cope with various channel conditions and robustness against out of band blockers. Maximum measured ranging error at 4 m in wireless link is 3.8 cm and total receiver consumption at 50 Mpulses/s rate is 50 mW.
