Abstract
A variable impedance output driver has been disclosed. One embodiment of the variable impedance output driver includes a first pull-up structure, a pull-down structure, and a comparator, coupled to the first pull-up structure and the pull-down structure, to calibrate the first pull-up structure and the pull-down structure against a reference impedance. Other embodiments are described and claimed.
