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.

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

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 ...

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 ...

This is a common emitter Colpitts oscillator. R1 and R2 form a voltage divider to provide base bias. the emitter resistor R3 also provides some bias. R4 is the collector resisotr across which the any ...
