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 ...

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 ...

Most simple circuits you'll find for measuring reactive components cover only a limited range of component values. Here's a circuit built from a handful of inexpensive parts that will let you measure ...

Of the three basic passive components—resistors, capacitors, and inductors—inductors are the least ideal and, therefore, the most difficult to model. The importance of a good model is that it not only ...

Inductors are more like a resistor in series with an ideal inductor, resistors can be inductors as well, and well, capacitors aren’t just simply a capacitance in a package. Little with electronics is ...

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 ...

ISSCC: Philips’ inductor capacitor has novel output buffer Steve Bush Philips Electronics has revealed a 35.2 to 37.6GHz inductor capacitor (LC) VCO at ISSCC. Made using a 70GHz fT, 100GHz fmax, SiGe ...

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 ...
