Abstract: Various apparatuses and methods are described where a signal is amplified using a chopper amplifier arrangement, and ripples caused by said chopper amplifier arrangement are reduced. In some cases, this reduction of ripples is performed by controlling a voltage offset of an amplifier of said chopper amplifier arrangement. In other embodiments, a detection of ripples or a chopping of the chopper amplifier arrangement is at least temporarily disabled.
