Abstract
An apparatus may comprise a skew detection circuit to sample a common mode voltage of a differential signal, wherein the sampled common mode voltage is indicative of an amount of skew between a first signal of the differential signal and a second signal of the differential signal; and a skew compensation circuit to adjust a delay of the first signal or the second signal based on the sampled common mode voltage to reduce the amount of skew.
