Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...

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 ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

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 ...

With this column we'll have a look at a few integrated passive devices, a tantalum capacitor, a SMT resistor, and one new power inductor. ON Semiconductor has integrated passive devices The High-Q ...

A few years ago, there was a stir about a new fundamental component called a memristor. That wasn’t the first time a new component type was theorized though. In 1948 [Bernard Tellegen] postulated the ...

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 ...
