Abstract

Comparateur de tension de haute précision en circuit MOS. Les tensions VA , VB sont appliquées à un circuit différentiateur 10, le signal de différence étant amplifié par l'amplificateur 24 à gain élevé, puis par un amplificateur intermédiaire 38 pour être appliqué à un circuit de verrouillage 46. Le couplage capacitif permet aux amplificateurs d'être polarisés indépendamment et d'éliminer les décalages de courant Pour une période de précharge les amplificateurs sont autopolarisés par une commutation qui les amene à un point d'operation désiré maintenu après la fin de la commutation. Les commutations sont chronologiquement espacées pour permettre d'absorber les impulsions transitoires. Puis les signaux sont comparés. Peut être utilisé dans tout circuit à transistor à effet de champ.
