Abstract
L'invention concerne un oscillateur comprenant un élément de résonateur en céramique ou en cristal piézo-électrique, à l'exclusion du quartz. L'oscillateur comporte également un condensateur connecté au résonateur et dont le diaélectrique est réalisé dans la même matière que l'élément de résonateur, de manière à corriger les déviations de fréquence d'oscillation dues à des variations de température. L'invention s'applique notamment à la réalisation de montres électroniques.
