The invention provides a signal transmission technique for transferring a high-speed digital signal of several tens of GHz band, while meeting the conventional system configuration and component configuration, as much as possible. A signal transmission system is provided in which the driver and the receiver comprise the logic circuit and the memory circuit for a transistor extending an entire electronic circuit, and wherein the driver is connected to the receiver via a signal transmission line, and to the power source Vdd via the power source/ground transmission line, and the receiver circuits and the driver and receiver all have substantially differential input and differential output, and at the output terminal of the substantially differential output of the driver there are no connections to a power source or a ground and the receiver receives signals by detecting potential difference of a substantially differential input signal and there are no distribution wires in the signal transmission lines. |
