Abstract
A multi-level point-to-point transmission system including at least one terminal resistor, a transmitter circuit, and a receiver circuit is disclosed. The transmitter circuit includes a first external resistor and a transmitter. The transmitter generates a first reference current according to the first external resistor and determines a current flowed through an output terminal thereof according to a transmission data and the first reference current. The receiver circuit includes a second external resistor, a third external resistor, and at least one receiver. The receiver generates a second reference current according to the second external resistor and generates a reference voltage difference according to the second reference current and the third external resistor. The receiver judges a voltage at the receiving terminal thereof according to the reference voltage difference so as to receive the transmission data correctly.
