A bypass capacitor eliminates voltage droops on the power supply by storing electric charge to be released when a voltage spike occurs. It also provides this service at a wide range of frequencies by creating a low-impedance path to ground for the power supply. What size bypass capacitor do we need?
The first line of defense against unwanted perturbations on the power supply is the bypass capacitor. A bypass capacitor eliminates voltage droops on the power supply by storing electric charge to be released when a voltage spike occurs.
Bypass Capacitors are generally applied at two locations on a circuit: one at the power supply and other at every active device (analog or digital IC). The bypass capacitor placed near the power supply eliminate voltage drops in power supply by storing charge and releasing them whenever necessary (usually, when a spike occurs).
Hence, when selecting a capacitor for bypassing power supply from internal noise of the device (integrated circuit), a capacitor with low lead inductance must be selected. MLCC or Multilayer Ceramic Chip Capacitors are the preferred choice for bypassing power supply. The placement of a Bypass Capacitor is very simple.
Almost all analog and digital devices use bypass capacitors. In both these devices, a bypass capacitor, usually a capacitor or value 0.1µF, is placed very closely to the power pins. Power supply sources also use bypass capacitors and they are usually the larger 10µF capacitors.
A simple and easy solution must be considered to prevent such a problem from occurring. This solution is the bypass capacitor. A bypass capacitor stores an electrical charge that is released to the power line whenever a transient voltage spike occurs.
