ABSTRACT:
A driver circuit including of one or more fingers, or parallel driver circuits, senses for an overshoot or an undershoot condition of the signal transmitted onto a transmission line coupled to the driver circuit and compensates for such an overshoot or an undershoot by temporarily turning off the offending transition portion of the driver circuit, or finger portion. This is accomplished by turning off the transistor applying one of the two supply voltages coupled to the output transmission line. Effectively, the compensation circuitry within the driver circuit more closely matches the output impedance of the driver circuit to the impedance on the driven transmission line.
