The oscillator is composed of three parts: Piezoelectric vibrator, its electro-mechanical system and a tunnel effect transistor (TET) so as to provide the positive feedback. The crystal vibrator makes use of the piezoelectric effect. When it receives a voltage, it will vibrate. The piezoelectric vibrator is connected to the electro-mechanical system. When the system oscillates, it will produce a voltage between the poles of the vibrator. In the same time, the TET will operate and the power amplifier will amplify the small impedance signal and create a feedback so as to maintain the feedback signal at a certain value with high stability. By doing this, it will reach a frequency that is determined by the electro-mechanical system of the crystal, thus generating a stable periodic signal.
