Abstract
An active compensation circuit is disclosed. In an embodiment a circuit includes a first compensation stage and at least one other compensation stage, wherein each of the first compensation stage and the at least one other compensation stage includes a sensor configured to provide a sensor signal being representative of a current flowing in one or more phases, a controlled current sink configured to supply a compensation current as a function of the sensor signal and an active amplifier element configured to provide a frequency response of an open circuit voltage amplification and/or is to supply a maximal output current, wherein the frequency response differs from a frequency response of at least one other active amplifier and/or wherein the maximal output current differs from a maximal output current of at least one other active amplifier.
