Title (EN) STRESS-IMPAIRED SIGNAL CORRECTION CIRCUIT
(FR) CIRCUIT DE CORRECTION DE SIGNAL DÉGRADÉ PAR UNE CONTRAINTE
Abstract:
(EN) In a system and method for correcting a stress-impaired signal in a circuit, a calibration circuit produces a first calibrated voltage based on a base-emitter voltage of one or more pnp transistors, a second calibrated voltage based on a base-emitter voltage of one or more npn transistors, and a voltage proportional to absolute temperature. A set of reference values are generated based on these voltages. A gain correction factor is calculated based on a function of the set of reference values and a set of temperature-dependent values, and the stress-impaired signal is corrected based on the gain correction factor.
(FR) L'invention concerne un système et un procédé de correction d'un signal dégradé par une contrainte dans un circuit, dans lesquels un circuit d'étalonnage produit une première tension étalonnée sur la base d'une tension base-émetteur d'un ou plusieurs transistors PNP, une seconde tension étalonnée sur la base d'une tension base-émetteur d'un ou plusieurs transistors NPN, et une tension proportionnelle à la température absolue. Un ensemble de valeurs de référence sont générées sur la base de ces tensions. Un facteur de correction de gain est calculé sur la base d'une fonction de l'ensemble de valeurs de référence et d'un ensemble de valeurs dépendant de la température, et le signal dégradé par une contrainte est corrigé sur la base du facteur de correction de gain.
