Abstract

PROCESO PARA CONVERTIR UN VALOR DE ENTRADA DIGITAL EN UN VALOR DE SALIDA ANALOGICO. LOS CONVERTIDORES DIGITO-ANALOGICOS UTILIZADOS PARA CONVERTIR UNA SEÑAL DIGITAL EN ANALOGICA TIENE UNA AMPLIA GAMA DE CUANTIFICACION PARA PROPORCIONAR LA MEJOR RESOLUCION POSIBLE. DICHOS CONVERTIDORES DIGITO-ANALOGICOS SON MUY CAROS. POR TANTO LOS CONVERTIDORES DIGITO-ANALOGICOS CON GAMAS DE CUANTIFICACION MAS ESTRECHAS SE UTILIZAN PARA CONMUTADORES DE SUBDIVISION FINA CONVERTIDOS A FUENTES QUE INTRODUCEN UN GRAN PASO AL ALCANZAR EL EXTREMO DE LA GAMA DE CUANTIFICACION Y SE VUELVE A RESOLVER LA NUEVA GAMA EN PASOS CORTOS UTILIZANDO EL CONVERTIDOR DIGITO-ANALOGICO. DEBIDO A LAS TOLERANCIAS Y DESGASTE DE LOS COMPONENTES, SURGEN UNA SERIE DE INCONSISTENCIAS EN EL CICLO DE SEÑAL ANALOGICO EN LOS PUNTOS DE CONMUTACION A OTRA GAMA. PARA EVITAR ESTAS INCONSISTENCIAS, SE INTRODUCE UNA TENSION DE UMBRAL DE SALIDA CERCA DE LA TENSION DE SALIDA MAXIMA DEL CONVERTIDOR DIGITO-ANALOGICO Y, CUANDO SE ALCANZA, SE ALMACENA EL VALOR TRANSMITIDO AL CONVERTIDOR DIGITO-ANALOGICO. DESPUES DE PASAR AL SIGUIENTE PASO GRANDE, EL CONVERTIDOR DIGITO-ANALOGICO EMPIEZA DESDE CERO. DESPUES DEL AUMENTO, EL VALOR DIGITAL TRANSMITIDO SE ALMACENA TAMBIEN AL ALCANZAR EL MISMO UMBRAL. DURANTE LA SALIDA DE SEÑAL, CUANDO SE RECORREN LOS VALORES DIGITALES, SE PASA AL SIGUIENTE PASO GRANDE AL ALCANZAR EL PRIMER VALOR ALMACENADO, TRAS LO CUAL EL SEGUNDO VALOR ALMACENADO ES TRANSMITIDO AL CONVERTIDOR DIGITO-ANALOGICO COMO EL VALOR INICIAL. APLICACION: CONVERTIDOR DIGITO-ANALOGICO.
