Abstract

CONVERTISSEUR NUMERIQUE-ANALOGIQUE ULTRA-RAPIDE. CE CONVERTISSEUR UTILISE UN CIRCUIT LOGIQUE A EMETTEURS COUPLES. DES RESISTANCES EN PROGRESSION GEOMETRIQUE DE RAISON 12 SONT CONNECTEES SUR LES EMETTEURS DES TRANSISTORS D'AMPLIFICATION DU CIRCUIT LOGIQUE. LE COURANT DE CONVERSION EST PRELEVE SUR UNE LIGNE DE CHARGE ADAPTEE. APPLICATION EN ELECTRONIQUE A LA CONVERSION NUMERIQUE-ANALOGIQUE ULTRA-RAPIDE.ULTRA-FAST DIGITAL-ANALOGUE CONVERTER. THIS CONVERTER USES A TORQUE TRANSMITTER LOGIC CIRCUIT. REASON 12 GEOMETRICAL PROGRESS RESISTORS ARE CONNECTED TO THE TRANSISTORS OF THE LOGIC CIRCUIT AMPLIFICATION TRANSISTORS. THE CONVERSION CURRENT IS TAKEN FROM A SUITABLE CHARGE LINE. APPLICATION IN ELECTRONICS TO ULTRA-FAST DIGITAL-ANALOGUE CONVERSION.
