![]() ![]() The quartz crystal is made from thin piece of quartz wafer tightly fitted and controlled between two parallel metalized surfaces. This is the symbol of Crystal Oscillator. Quartz Crystal and its Equivalent Circuit These changes produce very stable vibration, and as a Piezo-electric effect produces the stable oscillations. When voltage source is applied across it, it will change shape and produce mechanical forces, and the mechanical forces revert back, and produce electrical charge.Īs it convert energy electrical to mechanical and mechanical to electrical it is referred as Transducers. It produces a characteristic, identified as Piezo-electric effect. It reacts when a voltage source applied to quartz crystal. ![]() ![]() Quartz is mineral composed of silicon and Oxygen atoms. In such situation, the Quartz Crystal is used. The stability can be improved to a certain level in case of RC and RLC circuit, but still the improvement is not sufficient in specific cases. The temperature changes affect the load and power supply line which in turn affects the stability of the Oscillator circuit. In case of RC (Resistor-Capacitor) or RLC (Resistor-Inductor-Capacitor) Oscillators, they are not good choice where stable and accurate oscillations are needed. A proper good oscillator produces stable frequency. An oscillator is a mechanical or electronic construction which produces oscillation depending on few variables. In our previous RC Phase Shift Oscillator and Wein Bridge Oscillator tutorials, we get fair idea about what is an Oscillator. ![]()
