With board-level operating frequencies exceeding the resonant frequencies of most MLCCs, parasitic inductances of capacitors are determining decoupling performance. The lower the equivalent series ...

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 ...

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 ...

High-current, point-of-load (POL) buck converters leverage metal-oxide semiconductor field-effect transistors (MOSFETs) to provide the pulse-width-modulation (PWM) pulse train to the output filter.

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 ...

The ubiquitous power-rail decoupling capacitor, located as close to its load as possible, has a thankless role and often gets little respect, as compared to the functions of high-performance analog ...
