Claim:
1. A differential driving circuit comprising: a first driver for driving a first pad to a first voltage according to a first driving signal; a second driver for driving the second pad to a second voltage according to a second driving signal; a first capacitor for receiving a first voltage change of the first pad at one end thereof to transmit the first voltage change to the other end thereof in a transition interval in which voltages of the first and second pads are changed; a second capacitor for receiving a second voltage change of the second pad at one end thereof to transmit the second voltage change to the other end thereof in the transition interval; a transition interval voltage adder circuit for adding the first and the second voltages respectively transmitted thereto through the first and second capacitors; and a transition interval asymmetry compensation circuit for compensating asymmetry between slew rates of the first and second drivers in the transition interval by adjusting a slope of at least one of the first and second driving signals according to the added voltage from the transition interval voltage adder circuit.
