Abstract

La présente invention se rapporte aux circuits démultiplicateurs de la fréquence de signaux périodiques. Le circuit selon l'invention permet la division de la fréquence de deux signaux en opposition de phase diamétre 1 (t) et O2 (t). Un registre à décalage 10 comprend un ensemble de transistors, et de condensateurs qui forment une pluralité de chaînons branchés les uns à la suite des autres, chaque chaînon étant constitué de deux demi-chaînons identiques qui sont connectés en série et peuvent être alimentés respectivement par lesdits signaux périodiques. Des moyens de détection d'états particuliers du registre comportent les transistors MOS T8 T9 ; T10 Des moyens de production d'un signal de fréquence sous-multiple de celle desdits signaux périodiques comprennent les transistors T11 et T12 , le transistor Tl3 , le condensateur C7 et le condensateur C9 . Application notamment dans les montres à quartz.
