quartz crystal circuit
The equivalent electrical circuit for the quartz crystal shows a series RLC circuit, which represents the mechanical vibrations of the crystal, in parallel with a capacitance, Cp which represents the electrical connections to the crystal. Quartz crystal oscillators tend to operate towards their “series resonance”.
Quartz Crystal and its Equivalent Circuit This is the symbol of Crystal Oscillator . The quartz crystal is made from thin piece of quartz wafer tightly fitted and controlled between two parallel metalized surfaces.
The quartz crystal oscillator circuit diagram consists of series resonance and parallel resonance, i.e., two resonant frequencies. If the reactance produced by capacitance C1 is equal and opposite to the reactance produced by inductance L1, then the series resonance occurs.
The crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. The rate of expansion and contraction of the quartz is the resonant frequency, and is determined by the cut and size of the crystal.
This article will help you to design crystal oscillator circuit and understand its operation. This Quartz Crystal material is produce constant oscillation at different temperature ranges, and it is naturally available so the quartz crystal is inexpensive.
Quartz crystal is the most common type of piezoelectric resonator, in oscillator circuits we are using them so it became known as crystal oscillators. Crystal oscillators must be …
