摘要：

This paper presents a CAN bus transceiver with phase preserving dual-rail converters to implement a secure authentication method. An inherent auxiliary data channel is embedded in the transmitted primary data via phase modulation for data authentication. The enhanced rail converters presented here are implemented to provide single-rail to dual-rail data conversion and vice versa for data transmission while preserving the phase-modulated security signatures. The rail converters not only preserve the phase information of the transmitted data across different PVT corners but also provide significant suppression of phase errors caused by the phase mismatch between the dual-rail signals.
