What is another word for feedback circuit?
Pronunciation: [fˈiːdbak sˈɜːkɪt] (IPA) 
A feedback circuit is an electronic circuit that takes the output of an amplifier, filters it, and feeds it back into the input. It is used to stabilize the output voltage or current of the amplifier. Some synonyms for the term "feedback circuit" include control loop, closed loop, servo loop, and regulatory circuit. These terms all refer to the same concept of using a portion of the output signal to adjust the input signal, creating a feedback loop that regulates the performance of the circuit. Feedback circuits are commonly used in audio amplifiers, temperature controllers, and other electronic applications where precise control is required.
