Signal transmission circuit, signal output circuit and termination method of signal transmission circuit
This invention provides a signal transmission circuit, a signal output circuit, and a termination method of a signal transmission circuit capable of preventing the re-reflection of the signal at a transmitting node of a transmission path even when an impedance of a signal output circuit does not match a characteristic impedance of a transmission path. On a signal transmission circuit composed of a transmission path, a signal output circuit connected to a transmitting node of the transmission path, and a signal receiver circuit connected to a receiving node of the signal transmission path, in order to prevent the re-reflection of an output signal of a signal output unit at the transmitting node via the receiving node, a correction current generator unit is provided for outputting correction current with a predetermined current amount and at a predetermined timing set in a current amount/timing control section, to the transmitting node.
