| Whenever a chip operates, its current consumption changes rapidly. Even a short PCB trace has some resistance and inductance, which means the supply voltage at the chip can momentarily dip or fluctuate as the chip switches on and off internally. | Whenever a chip operates, its current consumption changes rapidly.

| Without proper decoupling, these small voltage fluctuations can become a source of noise and may affect the operation of the chip itself or nearby circuits. | Without proper decoupling, these small voltage fluctuations can become a source of noise and may affect the operation of the chip itself or nearby circuits. | ||
