What Are Decoupling Capacitors?

As you likely know, capacitors are used in electronic circuits to provide local energy storage and stabilize power supply voltage. Decoupling capacitors are a specific type of capacitor used to isolate or decouple two circuits. In other words, these capacitors decouple AC signals from DC signals or vice versa. Decoupling capacitors act as a buffer, supplying clean and stable power to components, which minimizes the risks of malfunctions, noise coupling, or signal integrity issues.
