As we have seen in part I and part II of this series [1], there are no inherent wear-out mechanisms in ceramic capacitors. And yes, as covered in part II, the high dielectric Class 2 capacitors (X7R) ...

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

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 ...

If you’ve been building circuits for any length of time, you probably know you need decoupling capacitors to keep your circuits stable. But even though it’s a favorite technique of ours, just ...

Deep-submicron systems-on-a-chip (SoCs) require a power-grid voltage drop of much less than 10% of VDD. Decoupling capacitors, or decaps, help achieve this goal by minimizing switching noise.

The 100% encapsulated SE4 metallized surface-mount power-supply decoupling capacitor series offers superior performance to unencapsulated polyphenylene-sulphide (PPS), polyester, and ceramic ...

Previously on “Yet More…” we looked at the impedance of a typical regulator and decoupling capacitor combination, and showed what happened when you 'shock' it with some dynamic current consumption.

The inability to supply adequate power in time can result in intermittent board failure and hours troubleshooting in the lab. Even an IC with ample current supply can experience “power shortage” if ...
