Abstract
A driver circuit that outputs a data signal uses feedback of the data signal to the driver circuit to modulate a drive strength of the driver circuit. The driver circuit has a pull-up driver stage and a pull-down driver stage. The pull-up driver stage uses a pull-up control circuit to modulate a drive strength of the pull-up driver stage dependent on a voltage of the data signal. The pull-down driver stage uses a pull-down control circuit to modulate a drive strength of the pull-down driver stage dependent on the voltage of the data signal.
