Abstract

This work presents a FlexRay Transceiver (FRT) used in an in-vehicle network compliant with the latest FlexRay physical layer standards. The proposed FRT utilizes a delay-based mechanism to reduce glitches. Besides, an Over-current Protection (OCP) circuit is included to avoid short-circuit hazard. The proposed is implemented on silicon using a typical 0.18 μm CMOS process. The total core area is 0.774 × 0.565 mm² and the power consumption is 158.4 mW at 10 Mbps data rate.
