6 FAQs about [What is a stable capacitor circuit]
Do input and output capacitors decrease stability?
Input and output capacitors always decrease stability. Input capacitors are a pole in the open-loop transfer function, but they are a zero in the closed-loop transfer function. The closed-loop zero increases the circuit (not the op amp) bandwidth, so sometimes input capacitors are added to the circuit to improve high-frequency response.

It is typically used to smooth out voltage fluctuations, store charge for energy bursts, and filter signals. Capacitors do all sorts of things on circuit boards, from managing power to processing signals.
Why do you need a capacitor?
Capacitors store energy in an electric field. They let it go when they need to so your circuit works right. That’s why you need them to smooth out power, filter out noise, and give you a little extra energy when you need it. For example, capacitors are critical in power supply circuits. They store energy and help regulate the voltage.
