Abstract
This paper presents a fully integrated flexible
ultra-low power UWB impulse radio receiver , capable of cm-ac-
curate ranging. Ultra-low-power consumption is achieved by
employing the quadrature analog correlating receiver archi-
tecture, by exploiting the duty-cycled nature of the system, by
operating in the sub-1 GHz band as well as by careful circuit
design. Two pulse rates, 39.0625 Mpulses per second (Mpps) and
19.531 Mpps, and a wide range of processing gains (0–18 dB) are
supported. Also, t
