ABSTRACT:
A differential signal transmission system includes m different voltage/current supplies, n transmission end, and a controller. The controller includes m×n switches. Each of the switches is coupled between a voltage/current supply and a transmission end. The controller controls the switches to turn on or off for coupling each transmission end to one of the different voltage/current supplies so as to carry the voltage of the coupled voltage supply onto the transmission end according to the transmitting data. The sum of the voltage differences among the transmission ends is 0.
