Abstract
Systems and methods for enhancing slew control of output signals. An output driver receives an input signal and controllably increases the gain of that signal to provide a high quality output signal for use by an electronic device coupled thereto. The output driver includes an operational amplifier that maintains stability of the output signal through a feedback of the output signal. A control circuit supplies a signal to the output driver such that the driver to improve the shape of the output signal as the input signal is applied. After the operational amplifier regains control, the control circuit disengages. One embodiment of the present invention may be particularly useful as a USB output driver.
