ABSTRACT:
A logic tracking interface circuit includes a signal comparator, a feedback comparator and a logic gate of the type to be driven by the interface circuit. The mean of the inverting and noninverting outputs of the signal comparator is applied as an input to the feedback comparator, the other input being provided by the logic gate. The inverted output of the feedback comparator is used to control the common mode of the signal comparator.
