Amplifier device with feedback and feed-forward control

An amplifier device, comprising:

• a signal input;
• amplifier circuitry comprising an amplifier input and an amplifier output;
• a feed-forward signal path;
• first signal combining circuitry configured to generate an error signal representative of a difference between a reference signal received at the signal input and a signal proportional to a signal at the amplifier output;
• signal processing circuitry configured to process the error signal to obtain a first signal;
• and
• second signal combining circuitry configured to combine the first signal and a signal of the feed-forward signal path to obtain a combined signal at an output of the second signal combining circuitry coupled to the amplifier input;
• wherein the signal processing circuitry comprises a limiter and a loop filter;
• wherein the limiter is configured to limit an amplitude of a second signal to a predetermined value to obtain a limited signal, wherein the second signal is the error signal or a signal representative of the error signal;
• and
• wherein an output of the limiter is coupled to an input of the loop filter, wherein the loop filter is configured to process the limited signal to obtain the first signal.
