When designing or optimizing a VRM (voltage Regulation Module), we need its output impedance data and impedance data for the filter inductors and capacitors for us to have complete simulation models.

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 ...

Using circuit simulating software like SPICE can be a powerful tool for modeling the behavior of a circuit in the real world. On the other hand, it’s not always necessary to have all of the features ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. During impedance matching, a specific electronic load (R L) is made to match a generator output impedance (R g) ...

Last weekend I finally got down to testing a prototype of a power amplifier I had been designing for a while. This amp has a bit of a unique output topology, and I was keen to see how it behaved when ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...
