Most ICs need to be decoupled from their power supply, usually with a 0.1uF capacitor between each power pin and ground. Decoupling is usually used to remove noise and to smooth power fluctuations.

Make sure the supply current goes to capacitor first, and only then to the IC Each integrated circuit should have at least a decoupling capacitor placed in close proximity to the supply pins. The ...

Choosing decoupling-capacitor values can seem to be a “no-brainer.” Unfortunately, even though the consequences of selecting the wrong values are often serious, the most commonly used methods usually ...

Decoupling capacitors have long been an important aspect of maintaining a clean power source for integrated circuits, but with noise caused by rising clock frequencies, multiple power domains, and ...

Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...
