Abstract
A high-speed bus includes a bus line to be connected with a bus driver and a bus receiver. Pull-up resistors are connected to both ends of the bus line for feeding a given pull-up electric potential thereto. A series resistor is further connected between the bus line and each of the bus driver and the bus receiver. The bus driver includes a series resistor and a capacitive component which are connected in series between the bus line and the ground. The bus receiver includes a waveform shaping component connected to the bus line for shaping a waveform of an inputted signal, and a receiver circuit receiving as an input thereof an output of the waveform shaping component.
