Abstract
The impedance of a driver driving a load on the other end of a transmission line is dynamically changed to improve slew rate and glitch termination. The driver is controlled to have a low impedance during an initial part of an edge transition, giving the strong drive needed at that time. At a first predetermined position in the edge transition, approximately equal to the flight time, the driver impedance is raised to a value approximately equal to the transmission line impedance to effectively terminate any reflected signals.
