Abstract :
This paper presents a reduction method of the start-up time after the switch-on of the D.C. power supply of a crystal oscillator circuit. It is shown that a fast start-up crystal oscillator can easily be obtained by changing only the circuit connection of the crystal resonator. The new scheme can be applied to the usual Colpitts crystal oscillator circuits, to the cascode crystal oscillator circuits, and also to the overtone crystal oscillator circuits
