Abstract
A deice maximizes the allowable granularity of adjustment of a bus driver line characteristics by compensating for temperature variations by selecting components that have an opposite and approximately equal thermal coefficient. In the first aspect, component parts may be made smaller because their tolerances need not be made so precise. In the second aspect, duplicating the circuitry with matching characteristics allows one circuit to be operational while the other circuit is tested or dormant. Switching between the two circuits is performed seamlessly with no interruption of device operation.
