Decoupling and Bypass Capacitors: Function and Application

Local Decoupling Capacitors. There are two main purposes: stabilizing the power supply voltage of the integrated chip and providing a high-frequency channel for the chip''s transient current. This reduces radiated noise and suppresses impedance coupling. Place these capacitors as close to the chip as possible between its power and ground terminals.
