Abstract

L'invention concerne les comparateurs de tension en circuit intégré. Un comparateur de tension comprend deux transistors MOS à canal P, 5 et 7, et deux transistors MOS à canal N, 6 et 8. Les transistors sont branchés de façon que le comparateur fonctionne correctement avec des signaux d'entrée faibles, et avec une faible consommation. Application aux montres électroniques.
