Abstract: For one disclosed embodiment, a driver may generate an output signal on a line. A predriver may receive an input signal and control the driver in response to the input signal to help improve symmetry of rise and fall transitions in the output signal. Other embodiments are also disclosed.

Abstract: A method and an apparatus to provide time-based edge-rate compensation have been disclosed. In one embodiment, the apparatus includes a reference pad, a reference circuit coupled to the reference pad, the reference circuit being operable to charge and to discharge a reference voltage at the reference pad, and an edge-rate detection and measurement circuit coupled to the reference pad to detect and to measure an edge-rate of the reference voltage at the reference pad. Other embodiments have been claimed and described.
