In one embodiment, an integrated circuit is disclosed that includes an AC coupler and a DC-level shifter. The AC coupler is configured to receive a differential input signal at first and second nodes, and to shift a common-mode voltage of the differential input signal. The DC-level shifter is coupled to the first and second nodes, and configured to reduce wander of the AC coupler. In various embodiments, the DC-level shifter is configured to supply a differential reference signal to the AC coupler, and to create the differential reference signal from the differential input signal at the first and second nodes by changing a common-mode voltage of the differential input signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Compensating for wander in AC coupling data interface","description":"Techniques are disclosed relating to reducing wander created by AC couplers.
