Crystal oscillator pdf

One of the most important features of any oscillator is its frequency stability, or in other words its ability to provide a constant frequency. Matthys, Robert J. Army Signal Corps funded an intense quartz crystal de. Jun In other words, crystal oscillators have found new impor- tance for their low phase noise in addition to their long-term frequency stability.

Ceramic resonators. Typical LC oscillator circuits are the Hartley, Colpitts and Clapp circuits. Oscillation conditions. A crystal oscillator is a circuit that uses a piezoelectric crystal.

Initially, we will look at a few basic oscillator circuits that use a LC tuned circuit. Later we will look at crystal basics and how crystal oscillators operate.
