Abstract: An apparatus for performing baseline wander correction is provided. The apparatus may include: a plurality of filters, a common mode voltage generator, and a compensation circuit. The plurality of filters may filter a set of input signals to generate a set of differential signals, the common mode voltage generator may generate a common mode voltage between the set of differential signals, and the compensation circuit may perform compensation related to baseline wander correction on the set of differential signals. Multiple current paths of the compensation circuit are associated with each other. Through a first current path and a second current path within the current paths, the compensation circuit may perform charge or discharge control on a first capacitor and a second capacitor within the plurality of filters to dynamically adjust compensation amounts of the compensation, to reduce or eliminate a baseline wander effect of the set of differential signals.
