Abstract
A differential driver circuit is configured to automatically adjust its source resistance to be substantially similar to a termination resistance. The differential driver circuit includes a variable resistance circuit on each leg of the differential driver circuit. A replica of one leg of the differential driver circuit is configured for adjusting the variable resistance circuits so that the differential driver circuit's source resistance appears to a load as substantially similar to the termination resistance.
