Skew is reduced by extracting the AC component of an input signal and superimposing it on a common reference voltage to produce a resulting voltage. The resulting voltage is provided as an input to a comparator, which compares it to the reference voltage to provide a final output. Thus, all signals fed to a system, in accordance with an embodiment, are referenced at the same DC level and hence, skew is reduced.
