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 ...

Inductors have the exact opposite characteristics of capacitors. Inductors store energy in a magnetic field (produced by the current through wire), whereas capacitors store energy in an electric field ...

Inductors designed with active elements are very desirable to designers today because conventional spiral inductors are too big, too heavy, and too costly, and they require tuning. During the last few ...

With their ability to resist changes in current, inductors are one of the basic but fundamental components used in electronics where current and voltage change with time. This tutorial provides an ...

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 ...

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 ...

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

For the PDF version of this article, click here. In all switching regulators, the inductor is used as an energy storage device. When the semiconductor switch is on, the current in the inductor ramps ...
