Abstract
L'invention concerne un filtre transversal. Dans un filtre transversal comportant un registre à décalage et des circuits de pondération formés par des couples de condensateurs sur un substrat semi-conducteur 1, au moins un circuit de pondération possède une région dopée 2 munie d'une indentation dans laquelle est inséré un premier condensateur à couche isolante ou à couche d'arrêt (électrode 3), qui comporte une indentation, dans laquelle est inséré un second condensateur à couche isolante ou à couche d'arrêt (électrode 4). Application notamment aux filtres pour signaux analogiques.
