Many applications call for wide-range-tunable LC oscillators that can deliver a nearly constant-frequency, nearly harmonic-free output even when the circuit's output load changes. From a design ...

We wish that all the beautiful animations that are available today to understand math and electronics had been around when we were in school. Nonetheless, they are there for today’s students and ...

[Martin] sent in a great guide to a simple Arduino based theremin. It’s a very small build – just a single common IC and some passive components – and easy enough to build in an afternoon. The ...

Glen Chenier’s blog I reposted yesterday got me thinking about other LC measurement techniques, including an inductance checker I built about 40 years ago and haven't used in nearly as long. The ...

Voltage-controlled oscillators (VCOs) are pivotal components in modern communications and signal processing, where their ability to generate a stable yet tunable signal is paramount. The performance ...

The master timing control circuit for most electronic applications is a precision signal source. For digital applications, it’s an accurate clock. In RF applications, it’s a carrier source for a ...
