Title (EN) D/A CONVERSION METHOD AND D/A CONVERTER
(FR) PROCEDE DE CONVERSION NUMERIQUE/ANALOGIQUE ET CONVERTISSEUR NUMERIQUE-ANALOGIQUE
Abstract: front page image
(EN)A D/A converter includes a triangular unit weight array (WA). A decoder (D) transforms digital samples into control signals (x[1], ..., x[5]) having a linearly weighted binary representation. These control signals are used for activation/deactivation of entire rows (columns) of the triangular unit weight array. Finally the unit weights are combined into an analog output signal.
(FR)L'invention concerne un convertisseur numérique-analogique comportant un réseau de charge spécifique (WA) triangulaire. Un décodeur (D) transforme les échantillons numériques en signaux de contrôle (x[1], ..., x[5]), possédant une représentation binaire de charge linéaire. Ces signaux de contrôle servent à activer/désactiver des rangs entiers (colonnes) de réseau de charge spécifique (WA) triangulaire. Enfin, les charges spécifiques sont combinées en signaux de sortie analogiques.
