An amplifier circuit comprising:



an amplifier;
an output limiter for providing a variable impedance comprising:

a first and second limiter terminal; a transistor comprising a conduction channel; a first resistor coupled in parallel with the conduction channel; and a capacitor coupled in series with the conduction channel between the conduction channel and the first or second limiter terminal; and


a feedback control unit comprising a comparator block configured to provide a control signal to the output limiter based on a comparison of the amplifier output signal and a setting voltage;
wherein: the first limiter terminal is coupled to the amplifier input or output; the second limiter terminal receives a reference voltage; and wherein receipt of the control signal at the transistor provides for a variable impedance for the amplifier circuit dependent on the amplifier output signal.
