ABSTRACT:
A bus interface system and method includes a driver circuit and a receiver circuit coupled on opposite ends of a conducting line of a bus. The driver circuit drives an adjustable current through the conducting line to the receiver circuit. The current level of the adjustable current can be adjusted to one of several levels according to the data item being transferred across the line. The receiver circuit receives the adjustable current and detects the level of the current to identify the information encoded by the signal being transferred. The current level can be set to one of several values such that the information being transferred by the signal can be in one of several possible states. The system therefore is capable of encoding more data than binary systems. Higher data bus transfer rates can therefore be realized.
