Bus driver circuit of FlexRay transceiver system was fabricated and tested. the Bus driver circuit configured transmitter circuit and receiver circuit. In the verified circuit transmitter circuit, data0, data1, idle, and idle_lp are control signals decoded by a one-hot decoder and fed into the bus driver. Furthermore, a three comparator scheme is used to carry out bit slicing and state recognition at the receiver circuit end. The verified circuit was used as the Magna/Hynix 0.18㎛ process and supply voltage was 3.3V. As a result of chip test, It was confirmed the output waveform change according to the control signal. BD is normal operation to 500㎑. But, up to 500㎑, the output waveform is occurred distorted phenomenon.
