What is a Decoupling Capacitor?
In electronic circuits, it is often seen that there is an electrolytic capacitor near the power supply pins of the integrated circuit. This capacitor is a decoupling capacitor. Decoupling capacitors usually have two functions: one is energy storage, and the other is to remove high-frequency noise.
