Abstract

EN UN CONVERTIDOR ANALOGO-DIGITAL, SE CONECTAN FASES DE CONVERSION A/D DE UN BIT EN SERIE PARA RECIBIR UNA SEÑAL ANALOGA. CADA FASE DE CONVERSION INCLUYE UN CIRCUITO DE MUESTREO Y RETENCION PARA MUESTREAR UNA SEÑAL ANALOGA DESDE UNA FASE PREVIA, UN COMPARADOR PARA COMPARARLA CON UN NIVEL DE TENSION ESPECIFICADO PARA PRODUCIR UNA SEÑAL LOGICA EN UNO O DOS NIVELES DISCRETOS DEPENDIENDO DE SI LA SEÑAL RECIBIDA DESDE LA FASE PREVIA ES SUPERIOR O INFERIOR AL NIVEL ESPECIFICADO. LA SEÑAL RECIBIDA DESDE LA FASE PREVIA SE SUMA A UNA TENSION DE REFERENCIA PREVISTA DE UNA DE LAS POLARIDADES OPUESTAS DEPENDIENDO DEL NIVEL DE LA SEÑAL LOGICA PARA PRODUCIR UNA SEÑAL DE SALIDA ANALOGA. LAS FASES DE CONVERSION SUCESIVAS SE GESTIONAN PARA QUE LA SEÑAL ANALOGA SE TRANSFIERA DESDE CADA FASE A LA SIGUIENTE, Y LAS SEÑALES LOGICAS GENERADAS POR LAS FASES DE CONVERSION INDIVIDUAL SE RETARDAN PARA QUE APAREZCAN SIMULTANEAMENTE EN LOS TERMINALES DE SALIDA DIGITAL.
