Abstract

L'invention concerne un comparateur différentiel à transistors à émetteurs couplés qui compare un premier signal, en particulier un signal en dents de scie à la fréquence horizontale avec un second signal, en particulier une parabole à la fréquence verticale dans un téléviseur pour produire des impulsions, en particulier des impulsions à la fréquence horizontale dont la durée est modulée à la fréquence verticale. Selon l'invention, le comparateur est agencé pour compenser une composante en mode différentiel qui dépend de la température des sources de signaux. La compensation est obtenue par un élément sensible à la température 5 couplé dans le circuit d'émetteur de l'un des transistors 1 à émetteurs couplés. L'invention s'applique notamment à la correction des distorsions en coussinet dans les téléviseurs.
