ABSTRACT:
There is provided a differential current driving current type transmission system. The system includes a transmission line pair for transmitting a signal by a differential scheme; a transmission unit having a transmission circuit for making the transmission line pair have a current difference according to a logic value of a transmission signal and equalizing the transmission line pair at a predetermined timing, and a transmission controller for controlling the signal transmission of the transmission circuit and the equalization of the transmission line pair; and a receiving unit having an I-V converter circuit for mirroring a current difference of the transmission line pair and converting the current difference into a voltage difference, and a differential amplifier for amplifying the voltage difference of the I-V converter circuit.
