Since their invention more than a century ago, crystal oscillators have been foundational to electronic design. They allow ... their downsides though; a quartz watch might lose or gain a few ...

The instrument is an ELV FC-500, which for such an old design looks surprisingly modern. Its Achille’s heel in terms of accuracy is the plain crystal oscillator it uses as a frequency standard ...

As with bulk quartz crystals, tuning is difficult ... dual-gate MOSFET oscillators use two-port SAW resonators. The hybrid SAW design results in an excellent characterization of oscillator performance ...

Measurements confirm theoretical results. The quartz microbalance (QMB) is a quartz crystal coated by a chemically interactive material, so that the mass of the coated quartz depends on the chemical ...

The oscillator works in parallel resonant mode of the crystal. When a 32768Hz quartz crystal is connected to the pins XIN32K and XOUT32K, the oscillator will output 32768Hz square wave.

An oscillator that uses a quartz crystal to generate a frequency. Such devices generally output a fixed frequency, but some can be controlled by a tuning voltage over a small range. Contrast with VCO.
