Abstract
A pin electronics circuit for automatic test equipment includes first and second sampling circuits for sampling first and second legs of a differential signal produced by a DUT (Device Under Test). Timing signals activate the first and second sampling circuits to sample the legs of the differential signal at precisely defined instants of time to produce first and second collections of samples. To deskew the legs of a differential signal with respect to each other, corresponding features within the first and second collections are identified and a difference is taken between them. The differential skew can then be applied to correct measurements of differential signals.
