[Bertho] really enjoyed pawing through the pile of projects submitted to the 7400 logic contest. But one thing kept hitting him with the vast majority of the entries: decoupling capacitors were ...

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 ...

One of the longest running problems in PCB (printed-circuit-board) design has been trying to figure how much decoupling capacitors you need for your design. PCB engineers often use too much decoupling ...

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.

Myrtle Beach, S.C. – With inductance values as low as 15 picohenries, AVX Corp.'s LICA capacitor arrays perform high-speed decoupling for multiple signal paths in high-frequency switching applications ...

Because of their high ESL compared to ceramic, tantalum capacitors are not the optimum choice for high frequency decoupling. Paralleling tantalum capacitors for bulk capacitance and ceramic for high ...
