[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 ...

Sponsored by: Texas Instruments. A phase-locked loop, of course. A PLL frequency synthesizer plays a key role in delivering the precision and accuracy demanded by many applications. The master timing ...

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 ...

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 ...

The project is based on PIC16F628 and PIC16F84 microcontrollers to build an inductance/capacitance meter that can measure capacitance range from 0 to >0.1uF and inductance range from 0 to >10mH. The ...
