When designers think of passive components, they think of manufacturing tolerances for inductors and capacitors that are typically ± 20% or ± 10%. That's okay in theory, but not when these components ...

Giovanni D’Amore discusses approaches to characterising both dielectric and magnetic materials using impedance analysers and specialist fixtures. We are used to thinking about technological progress ...

Researchers at the University of Illinois, Urbana-Champaign have devised a method of combining capacitors and inductors in a tiny, 3D rolled membrane. This will save space in the electronic filters ...

This circuit for measurement of inductance and capacitance can be used to test whether the values of inductors and capacitors quoted by the manufacturer are correct. The principle used in the circuit ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

Mathieu Renaud, Senior Power Management Designer, Intégration Dolphin Inc. Yves Gagnon, Executive Director, Intégration Dolphin Inc. Inductor-based Switching Regulators (SR) have historically ...

Advanced semiconductor technology allows an increasing number of transistors to be integrated onto ever-smaller silicon chips. This increases the power density, however, and presents power-management ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal ...
