The interest of industry for localization technologies is growing, because of their ability to allow a wide variety of applications. Among the different technologies, UWB is known to potentially offer the best precision. This paper presents a fully integrated low-power UWB impulse radio receiver dedicated to communication and ranging applications. The new architecture based on double quadrature is used to reach sub-cm ranging precision while limiting the speed requirements and complexity of ADC and digital signal processing. Much attention has been paid to rejecting the out-of-band signals which could degrade receiver performance while fully exploiting the available spectrum in the [3-5 GHz] band. The 5.8-mm 2 0.13-mu; m CMOS receiver consumes 50 mW at 50-Mb/s maximum data rate. It shows 95-dBm sensitivity at 1 Mb/s and 2.5-mm maximum ranging error at 10 m. © 2013 IEEE.
