摘要

The major work of this paper is to design a Bus Driver for the physical layer of the FlexRay communication in an X-by-Wire vehicle electronic system. First, we design the digital state machine according to the FlexRay specifications [1, 2], and implement the external inpul/output signals and the internal signals that connect among each sub-circuit block. Second, we design a transmitter that can provide the capability of differentially transmitting binary data stream. Third, we design a receiver that not only can receive binary data stream, but also can filter noise and distinguish signal levels. Finally, we test the designed circuit. The testing results confirm the functionality of the designed Bus Driver. The design is based on a TSMC 0.35 u,m 2P4M mixed-signal CMOS process. For 10 MBit/s data rate, ±1.2 V transmitting voltages, and 45 Q bus equivalent resistance, the load and the transceiver dissipate 32 raW and 204 mW power, respectively.
