Abstract
A system may include a driver for driving an output signal to a load, a pre-driver for driving a pre-driver signal to the driver, the pre-driver having a variable drive strength, and a controller configured to control the variable drive strength based on at least one measured physical quantity to compensate for variation of an output signal edge rate due to variations in the at least one measured physical quantity.
