In 2008, Kendall Castor-Perry began an extended investigation into the effect that bypass capacitor selection has on analog circuit performance. Five years on, we’re reposting this classic series, ...

As Moore's Law has marched through the 1990s into the new millennium, each process node has brought a doubling of density with increased clock and data-transfer speeds and frequencies. Each node, ...

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 ...

Figure 1 shows a switching regulator that can generate a lower voltage from a high voltage. In this type of circuit, the bypass capacitor (CBYP) is especially important. It has to support the switched ...

The four basic capacitor types. The key parameters involved in selecting the right capacitor for automotive designs. Advantages and limitations of electrolytic and electrostatic capacitors. Choosing a ...
