摘要：

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.
