Crystal Oscillator Circuit Formula. Q factor of a crystal can be calculated using the following formula. Crystal oscillator circuit diagram.
This q factor determines crystal s frequency stability. The oscillator circuit consists of an inverting amplifier. Typical colpitts transistor crystal oscillator circuit.
Sometimes the q factor of a crystal is more than 200 000 also observable.
A more accurate term for it is piezoelectric resonator. A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric resonator a crystal as its frequency determining element. Lc f 2π 1 equation 1. Typical colpitts transistor crystal oscillator circuit.
