Abstract

UN CIRCUITO REDUCE EL NUMERO TOTAL DE RESISTENCIAS REQUERIDAS PARA OBTENER LAS TENSIONES DE REFERENCIA A LA PLURALIDAD DE COMPARADORES (60) EN UN CONVERTIDOR ANALOGICO A DIGITAL (10). EN TAL CIRCUITO, UNA FUENTE DE POTENCIAL DE TENSION (30) QUE TIENE UN PRIMER (1) Y UN SEGUNDO (2) TERMINAL ESTA ACOPLADO A UN CORDON DE RESISTENCIAS DE UNIDAD (50) QUE TIENEN UN PRIMER Y UN SEGUNDO EXTREMO Y UNA PLURALIDAD DE TOMAS ENTRE LOS EXTREMOS. UN PRIMER DISPOSITIVO ACTIVO (81) TIENE UNA ENTRADA ACOPLADA AL PRIMER TERMINAL (1) DE FUENTE DE POTENCIAL DE TENSION (30) Y UNA SALIDA ACOLADA AL PRIMER EXTREMO DEL CORDON DE RESISTENCIAS DE UNIDAD (50), UN SEGUNDO DISPOSITIVO ACTIVO (80) TIENE UNA ENTRADA ACOPLADA AL SEGUNDO TERMINAL (2) DE LA FUENTE DE POTENCIAL DE TENSION (30) Y UNA SALIDA ACOPLADA AL SEGUNDO EXTREMO DEL CORDON DE RESISTENCIAS DE UNIDAD (50).
