Title (EN) SEMICONDUCTOR CCD TRANSVERSAL FILTER WITH CONTROLLABLE THRESHOLD LEVEL
(FR) FILTRE TRANSVERSAL CCD SEMI-CONDUCTEUR AVEC NIVEAU DE SEUIL COMMANDE
Abstract: front page image
(EN)A filter in the form of a semiconductor charge coupled device (CCD) split-electrode transversal filter section (10) of many transfer stages, typically of the order of 150, is characterized by a controllable detection threshold level by means of the addition of an auxiliary CCD split-electrode section (20) of but a few stages, typically one or two. Each segment of a split-electrode (209) of this auxiliary section (20) is connected to the corresponding sense line of the transversal filter section (10).
(FR)Un filtre consistant en un filtre transversal a electrode fendue du type a dispositif couplage de charge (CCD) semi-conducteur (10) comprenant un grand nombre d"etages de transfert, de maniere caracteristique de l"ordre de 150, se caracterise par un niveau de seuil de detection qui peut etre commande par addition d"une section auxiliaire CCD a electrode fendue (20) ne com prenant que peu d"etages, de maniere caracteristique un ou deux. Chaque segment d"une electrode fendue (209) de cette section auxiliaire (20) est connecte a la ligne de detection correspondante de la section filtre transversale (10).
