Abstract
A current driver circuit has a current driver and a current compensation circuit. The current driver has a current source transistor connected to a power source potential level, while it is coupled to a pair of transmission lines. The current compensation circuit is coupled to the output side of the current source transistor for the compensation of an output current from the current driver in response to a common mode potential of the pair of transmission lines.
