Abstract

This paper deals with dual-mode crystal oscillator (DMXO) based on two modified Butler´s oscillators using a quartz resonator as frequency stabilization element and sensor element of its own temperature as well. The main attention is devoted to the amplitude condition of oscillations excitation. This issue was investigated by means of so called regeneration coefficient that was obtained for the treated DMXO. The knowledge of this measure is crucial at the startup of dual-mode oscillations.
