RECEIVER AND SIGNAL TRANSMISSION SYSTEM

摘要

PURPOSE: A receiver and a signal transmission system are provided to reduce variation of a current flowing through a transmission line, and do not need a terminal resistor connected to the transmission line. CONSTITUTION: A receiver for receiving a signal transmitted from a transmitter via a transmission line includes: a current control section for allowing a current to flow into the current control section from transmission line or flow from the current control section to the transmission line, wherein the current has an amount which varies according to a logical level of the signal and flows in a same direction irrespective of the logical level of the signal; and a determination section for determining the logical level of the signal based on the amount of current which has flowed from the transmission line into the current control section or based on the amount of current which has flowed out from the current control section to the transmission line.
