Decoupling Capacitor
Decoupling capacitors are mainly used to suppress high-frequency noise in the power supply signals. It takes small ripples, which could be harmful to the delicate ICs. It is also help in providing right amount of voltage supply to the circuit. If ever the power supply may drop temporarily its voltage which is a common thing, decoupling capacitor supply power briefly power to the circuit. That’s why such capacitors are known as bypass capacitors. As they act as the power supply and bypass the power supply. Decoupling capacitors are connected between the power source and the ground. Different valued capacitors are used as decoupling capacitors because some do better filtering of noise. Some of voltage supplies are placed far from the circuit. In such case any current from the connecting wires are sufficient to produce distortion. Due to this, the required input voltage may get change. When decoupling capacitors are placed it is always tried to place them close to the IC as possible. The far they are placed, the less effective they will be.
