ABSTRACT:
An embodiment of a differential output driver includes a driver to generate an inverted output signal in response to an input signal and a first control signal, and to further generate an output signal in response to an inverted input signal and a second control signal. The differential output driver also includes a controller to generate the first control signal and the second control signal in response to detecting a voltage difference between a first detected voltage difference between a reference voltage and the output signal, and a second detected voltage difference between the reference voltage and the inverted output signal.
