Abstract
L'invention concerne un circuit amplificateur de signal greffable au niveau microvolt qui peut être utilisé pour résoudre des signaux électriques générés par les nerfs en présence de signaux de plus grande amplitude générés par les muscles, le coeur ou des sources de bruit externes. Le circuit comporte un préamplificateur à faible bruit et à rapport de réjection en mode commun (CMRR) élevé, suivi d'une cascade d'étapes, qui assure le filtrage et l'amplification ultérieure du signal neutre. Le circuit amplificateur passe-bande peut également présenter un rapport de réjection d'alimentation (PSRR) élevé. Les données de sortie font l'objet d'une compensation de décalage par une étape de restauration du CC. Le circuit de protection nerveuse minimise ou bloque le débit du CC qui passe à travers les terminaux d'entrée en cas de défaillance des semi-conducteurs dans le préamplificateur. Il est possible d'intégrer le circuit à un circuit monolithique commun avec un circuit d'asservissement pour commander les dispositifs de simulation électrique fonctionnelle (FES).
