We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates.

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 ...

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

Emitter followers are well known for being prone to oscillation if they're feeding a capacitive load. The trait is shared however, with source followers, cathode followers ( Remember vacuum tubes?? ) ...

Using the power of Arduino, Evan Kale has ingeniously transformed a weed wacker into an Arduino-powered metal detector. This innovative project showcases the versatility and potential of Arduino in ...

We are always glad to see [Ken Shirriff] tear into something new and this month he’s looking inside a quartz oscillator module. Offhand, you’d think there’s not much to these. A slab of quartz and ...

A. Determine the frequency for the oscillator of the given circuit. Assume there is negligible loading on the feedback circuit and that its Q is greater than 10. B. Find the frequency if the ...
