  • Abstract This thesis is composed of two parts: a high-speed transceiver front-end design with fault detection for FlexRay-based automative communication systems, and a temperature detector.
    In the first topic, a high-speed transceiver design with a fault detection circuit compliant with FlexRay standards V2.1 is proposed and realized on silicon. According to FlexRay physical layer standards, a LVDS-like transmitter is utilized to drive the twisted pair to generate a pair of differential signals. By contrast, a three-comparator-based receiver will recover the signals and then detect the mode of the bus. A failure detector is added at the transmitter to detect the operating current magnitude to avoid any over-current hazard. Meanwhile, a short-circuit detector is added at the receiver to detect short-circuit faults to vdd or gnd.
      The second topic discloses a temperature detector circuit, particularly dedicated for the reliability of any in-car system by sensing the temperature and the process at the same time. A discharging circuit composed of four PMOS transistors discharges until the output voltage is stable. It is composed of several reference voltages and comparators to determine the range of temperature and process. Eventually, by identifying the process corner and the temperature range, the reliability and safty of the car electrics will be ensured.
