Resonant Frequency Analysis of Quartz Shear Oscillator
Publié en 2013
The most commonly used type of resonator is the AT-cut, where the quartz blank is in the form of a thin plate cut at an angle to the optic axis of the crystal. This paper reports the modeling of a quartz oscillator for a resonant frequency analysis based on piezoelectric effects. The proposed oscillator consists of a single quartz disc with two electrodes on the top and bottom surfaces of the geometry; one of them is grounded. An AC voltage is applied to the top electrode. Then a capacitor of 1 pF is introduced between the voltage source and the top electrode of the crystal. Further computation of the frequency response of the proposed device was done by adding different capacitors in series.
