Abstract

This paper presents the design techniques employed to minimize the irradiated noise emissions of a high speed controller area network (HSCAN) line driver targeted for automotive and industrial applications. Tradeoffs between this and other architectural approaches are presented, focusing on improved emissions without reducing robustness to EMI aggressions. This approach resulted in a complete CAN interface that does not require discrete filters or RF-chokes, lowering implementation costs while improving performance. The interface was successfully implemented in a 0.8mum BCD technology and experimental results are discussed. Finally, possible developments over the derived techniques are presented
