To minimize the ground impedance, the decoupling capacitor must be placed as close as possible to the IC power pin. When power fluctuation occurs, the decoupling capacitor stores the energy carried along with the transient current and shunts it directly to the ground, thus maintain a relatively constant voltage at the power pin of the device ...
