We present a fully asynchronous threshold-based IR-UWB receiver which enables a high sensitive distance es- timation. It includes an ultra-low power baseband unit which achieves 533 fJ/pulse with an asynchronous, multipath robust and time expiring energy detector, which embeds signal strength in the baseband processing latency to increase sensitivity to TX- RX separation. Asynchronous line-of-sight over-the-air measure- ments obtained with an integrated all-digital transmitter show a maximum sensitivity of 1 mm TX-RX separation per nanosecond system latency.

Abstract

We present a fully asynchronous threshold-based IR-UWB receiver which enables a high sensitive distance es- timation. It includes an ultra-low power baseband unit which achieves 533 fJ/pulse with an asynchronous, multipath robust and time expiring energy detector, which embeds signal strength in the baseband processing latency to increase sensitivity to TX- RX separation. Asynchronous line-of-sight over-the-air measure- ments obtained with an integrated all-digital transmitter show a maximum sensitivity of 1 mm TX-RX separation per nanosecond system latency. The RX also permits data communication based on the use of self-synchronized modulations.
