Abstract:
A signal transmitting/receiving apparatus, comprising:a transmitting device for transmitting data; a receiving device for receiving data; a data line for transmitting the data; and a supply line for transmitting a bias voltage for determining a voltage of the data line, wherein the transmitting device and the receiving device are connected to each other through the data line and the supply line, the transmit device comprising: a driver circuit for outputting the data to the data line; and a bias generating means for generating the bias voltage and outputting the bias voltage to the supply line, the receiving device comprising: a terminating resistor connected to the data line; and a receiver circuit for detecting the data from the data line, wherein the data line is connected to the supply line via the terminating resistor, so that a midpoint potential of the data line is determined via the supply line connected at a midpoint of the terminating resistor.
