ABSTRACT:
An apparatus for compensating slew rate of a driving circuit includes: a first circuit, for receiving an edge transition from the driving circuit and generating a first pulse proportional to an actual slope of the edge transition; a second circuit, for receiving an ideal edge transition of the driving circuit and generating a second pulse proportional to an ideal slope of the ideal edge transition; a comparison circuit, coupled to the first circuit and the second circuit, for comparing an extreme value of amplitude of the first pulse with an extreme value of amplitude of the second pulse to produce a comparison signal; and a control circuit, coupled to the comparison circuit, for increasing or decreasing the slew rate of the driving circuit according to the comparison signal.
