Quartz Crystal Oscillators The quartz crystal oscillator is a resonant device made using the piezoelectric effect of quartz crystals, and is capable of generating high-precision oscillation frequencies to provide stable clock signals for electronic systems. Working Principle Piezoelectric Effect: When a quartz crystal is subjected to mechanical stress, it generates an electric charge on its surface. Conversely, when an electric field is applied across the crystal, it undergoes mechanical deformation. This mutual conversion between mechanical stress and electric charge is known as the piezoelectric effect. When an alternating voltage is
