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 ...

[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 ...

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 ...

Dubbed Si500, “it generates any frequency from 900kHz to 200MHz and phase jitter is 2ps(RMS) maximum, 1.5ps typical”, said the firm. Period jitter at 100MHz is typically under 0.8ps. Silicon Labs has ...

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 ...

Terminus Circuits offers an Analog Phase Locked Loop which is a LC oscillator-based integer-N PLL IP powered at 900 mV. The PLL operates with input re ...
