Title (EN) COMPARISON CIRCUIT FOR ANALOG/DIGITAL CONVERTER
(FR) CIRCUIT DE COMPARAISON POUR CONVERTISSEUR ANALOGIQUE-NUMERIQUE
Abstract: front page image
(EN)The invention relates to a comparison circuit for an analog/digital converter. In order to reduce the effect of offset voltages from the different comparators of the comparison circuit, the invention comprises the downstream connection of the outputs (O) of the comparators (C), voltage followers (A) and a resistor network (2), said network (2) delivering as output (O', Ō´) the average voltages of those present at the outputs (O, Ō) of the comparators (C).
(FR)L'invention se rapporte à un circuit de comparaison pour' un convertisseur analogique-numérique. Afin de réduire l'effet des tensions d'offset des différents comparateurs du circuit de comparaison, on raccorde en aval des sorties (O) des comparateurs (C), des suiveurs de tensions (A) et un réseau de résistance (2) délivrant à ses sorties (O’, Ō´) des tensions moyennes de celles présentes sur des sorties (O, Ō) des comparateurs (C).
