Using my Multisim SPICE tool to analyze an oscillator, I ran into a little bit of simulation trouble. My circuit was a simple Colpitts oscillator and the simulation showed that it would indeed ...

I have been experimenting with passive crystal oscillators for over two decades, but while looking around, came across some great articles on active crystal oscillators. Last year I got a few ...

In the past, nanoelectromechanical resonators have been passive devices that required external oscillators to keep them working, so the development of a self-sustaining resonator powered only by a d.c ...

To alleviate the drawbacks of quartz oscillator technology, classic microelectromechanical systems (MEMS) materials are now being used to fabricate three-dimensional resonating structures. These ...
