Abstract
Various embodiments of the invention provide for an AC-coupling method and systems that utilize a nested loop circuit to generate a differential mode output that facilitates an offset compensation and a common mode output that facilitates DC-biasing of an active circuit. In embodiments, the nested loop circuit comprises a differential amplifier and a differential mode loop that generates a differential mode output and a common mode loop that uses a common mode voltage and a reference voltage to generate the common mode output.
