Abstract

L'invention concerne les filtres utilisant un dispositif à transfert de charges du type comprenant une partie récursive et une partie non récursive. Elle consiste à imbriquer une à une les cellules du dispositif correspondant à ces parties et à utiliser une fréquence d'échantillonnage du signal d'entrée moitié de la fréquence de transfert de charges. On minimise ainsi considérablement les effets de l'inefficacité de transfert. Elle permet de réaliser des filtres dont les performances sont meilleures tout en ne nécessitant pas de dispositif à transfert de charge de plus grande taille.
