Abstract

Un circuito reduce el numero total de resistores necesitados para proveer los voltajes de referencia de la pluralidad de comparadores (60) en un convertidor analogico-digital (10). En dicho circuito, una fuente de potencial de voltaje (30) que tiene primera (1) y segunda (2) terminales está acoplada a una cadena de resistencias (50) unitarias que tiene primero y segundo extremos y una pluralidad de tomas entre los extremos. Un primer dispositivo (81) activo tiene una entrada acoplada a la primera terminal (1) de la fuente de potencial de voltaje (30) y una salida acoplada al primer extremo de la cadena de resistencias unitarias (50). Un segundo dispositivo activo (80) tiene una entrada acoplada a la segunda terminal (2) de la fuente de potencial de voltaje (30) y una salida acoplada al segundo extremo de la cadena de resistencias unitarias (50).
