Abstract
This paper presents an impulse-radio ultra-wideband (IR-UWB) receiver design for precise wireless ranging using a newly proposed direct sampling with time-extension (DTE) method. To overcome the problems encountered in high-speed sampling for impulse signals, the DTE method, which exploits the characteristics of an impulse, is proposed. The proposed method performs high-speed sampling only during the period when short pulses exist, and quantizes the sampled signal during the dead time where no pulses exist. The high-speed impulse signal can be easily digitized using low-speed analog-to-digital converter. We designed and fabricated the IR-UWB receiver using a 65-nm CMOS process. The measurement result shows a 1.9-mm resolution for indoor wireless ranging within a 1-m range. The receiver has a power consumption of 70 mW at 1.2 V and energy efficiency of 1554 nJ/pulse.
