Which of the following effect illustrate the basic working of a quartz crystal oscillator?(a) Photovoltaic effect(b) Piezo electric effect(c) Electro-magnetic effect(d) Electron excitation effectThe question was asked during an interview for a job.My query is from Crystal Oscillator-2 topic in portion Oscillators of Analog Circuits

Answer»

Right choice is (b) Piezo ELECTRIC effect

To explain: When a voltage source is applied to a quartz CRYSTAL, it begins to produce a CHARACTERISTIC known as the Piezo electric effect. It is a property of a crystal by which an ELECTRICAL charge produces a MECHANICAL force by changing the shape of the crystal and vice versa, a mechanical force applied to the crystal produces an electrical charge.
