Examine a traditional Hartley oscillator circuit, and you’ll note its trademark: a tapped inductor that determines the frequency of oscillation and provides oscillation-sustaining feedback. Although ...
[Scott Harden] has been working through a design for a variable inductor to use as a PTO, or permeability tuned oscillator. What you see above is the most recent fruit of these efforts. The variable ...
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 ...
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 ...
The laptop I’m using, found for 50 bucks in the junk bins of Akihabara has a CPU that runs at 2.53GHz. Two billion five hundred and thirty million times every second electrons systematically briefly ...
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 ...
Everyone interested in analog electronics should find some value in this post. Of course, an effort has been made here to make the content understandable to relative newbies. Forget about complex ...
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 ...
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 ...
