A high speed transceiver front-end design with fault detection for FlexRay-based automotive communication systems

Abstract

This paper presents a high speed transceiver design with fault detection circuit compliant with FlexRay standards V2.1. An LVDS-like transmitter is utilized to drive the twisted pair of the bus. A current detector is included in the transceiver to detect the operating current so as to prevent over-current hazard. By contrast, a 3-comparator scheme is used to carry out the required bit-slicing and state recognition in the receiver of the bus. A bus line short-circuit detector is also included in the proposed receiver design.

“…Detection theory is fundamental to designing decision making system in signal processing problems. Applications of signal detection include radar signal detection [111], sonar signal processing [112], communication system [113], image processing [114], speech signal detection [115] and many others. Two most frequently used methods in signal detection are the Neyman-Pearson theorem (NP) [67] and the Bayesian approach [12], respectively, where NP detector is more suitable for signal detection in sonar/radar applications while the Bayesian approach is more appropriate for signal detection in communication systems.…”
