In “Know the sometimes-surprising interactions in modelling a capacitor-bypass network” (abbreviated to “Know the…” when referred to here), Tamara Schmitz of Intersil and I provided some simulation ...

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 ...

This is the last of the “Yet more…” series. One final plot twist, a moderately satisfying ending, and my work here will be done. Until the sequel, that is… Let the op-amp do the pinging! Instead of ...

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 ...

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 ...

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 ...
