If you’ve worked with microcontrollers or digital logic chips you probably know that you’re supposed to add a small capacitor in between the voltage and ground pins for decoupling purposes.

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… ...

Filling the Decoupling Gap Empower maintains that the silicon-capacitor technology fulfills the “last inch” decoupling gap from the voltage regulators to the SoC supply pins.

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 ...
