Abstract
Systems and methods are disclosed for providing output impedance measurement techniques. For example, in accordance with an embodiment of the present invention, a system includes a controller adapted to measure an output impedance of a first circuit that provides an output signal having a first voltage level. The output signal from the first circuit is compared to a plurality of voltage levels provided by the controller, with the controller determining the output impedance of the first circuit based on the results of the comparison.
