In this paper, a passive filter is proposed to support a star-like topology in a high-speed controller area network and to extend the length of the stubs. A high-speed controller area network requires a linear wiring topology, while an actual network may be configured as a star-like structure using joint connectors owing to productivity and cost concerns. This joint-connector-based controller area network configuration is likely to suffer from increased signal distortions caused by a larger transient voltage and impedance mismatch. Here, a passive filter for reducing these signal distortions in a joint-connector-based controller area network structure is proposed, which allows a star-like topology with extended stubs. The proposed passive filter is composed of a resistor and bead in series, which is easily inserted in a joint connector. With the proposed filter, the induced transient voltage and settling time in transition to a recessive state were reduced by 37% and 66% respectively. Thus, the proposed filter has the effect of improving the reliability of communication in the same wiring dimension or, equivalently, lengthening the stubs with the same reliability.
