Closed-loop Gain
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Closed-loop gain is the voltage gain of an amplifier when a negative feedback network is connected. It is determined by the feedback network and is typically much lower but more stable than the open-loop gain.
Example in context
“In an inverting amplifier configuration, the closed-loop gain is set by the ratio of the feedback resistor to the input resistor.”
“Ters çeviren amplifikatör konfigürasyonunda, kapalı döngü kazancı geri besleme direncinin giriş direncine oranıyla ayarlanır.”
Where engineers use it
Engineers calculate closed-loop gain to design amplifiers with precise, predictable behavior. It appears in feedback network design, stability analysis, and bandwidth calculations. Understanding it is essential for op-amp circuit design.
Synonyms: Acl, voltage gain with feedback
Antonyms: open-loop gain
Practice: can you use “Closed-loop Gain” at work?
You need to replace an op-amp with a lower open-loop gain variant. Determine how the closed-loop gain and bandwidth are affected in your existing circuit design.

“Design a non-inverting amplifier with a closed-loop gain of 10 using standard resistor values.”
