Sometimes the need arises to construct a really simple oscillator. This could hardly be simpler than the circuit shown here, which uses just three components, and offers five separate octaves, ...

Small inductance changes on the order of 0.01% can easily be sensed over a wide range with a simple circuit connected to a serial port (see the figure). Using a classic Colpitts oscillator interfaced ...

This article describes how to design and build an adjustable, encoder-controlled, two-range sine / square wave oscillator using the SLG47004 IC. To design a simple analog sine wave oscillator (using ...

Sometimes the best projects are the simple, quick hits. Easily designed, fast to build, and bonus points for working right the first time. Such projects very often lead to bigger and better things, ...

Crystal oscillators are fundamental components in modern electronic systems, providing the precise timing necessary for communication, computation, and sensor network operations. Recent advances in ...

Fig 1. Two analog multipliers form a VCO with quadrature outputs, while a third multiplier provides AGC to stabilize output voltages without adding distortion. Fig 2. The oscilloscope trace of the VCO ...
