Abstract

UN JUEGO DE N BITS DE DATOS DIGITALES CONECTADOS EN SERIE A UN NODO DE ENTRADA SE CONVIERTEN EN UNA TENSION ANALOGICA MEDIANTE N CONDENSADORES PONDERADOS EN BINARIO Y N TRANSISTORES DE CONMUTACION, ESTANDO UN CONDENSADOR ASOCIADO A UN TRANSISTOR DE CONMUTACION PARA CADA UNO DE LOS N BITS DE DATOS DIGITALES. CADA CONDENSADOR SE ENCUENTRA CONECTADO ENTRE UN NODO DE SALIDA Y A TRAVES DE LA VIA DE CONDUCCION DE SU TRANSISTOR DE CONMUTACION ASOCIADO A UN PRIMER TERMINAL DE FUERZA. SE UTILIZAN DOS TRANSISTORES PARA MUESTREAR SELECTIVAMENTE LOS N BITS DE DATOS EN SERIE Y PARA ACOPLAR Y ALMACENAR LOS DATOS MUESTREADOS EN LAS COMPUERTAS DE LOS TRANSISTORES DE CONMUTACION QUE SE ENCUENTRAN PRECARGADOS DE MODO QUE LOS DOS TRANSISTORES QUE ACOPLAN LOS DATOS EN SERIE SOLO NECESITEN COMPORTARSE EN EL MODO DE FUENTE COMUN. LOS DATOS EN SERIE APLICADOS A LAS COMPUERTAS DEL TRANSISTOR DE CONMUTACION SON TRANSFERIDOS A LOS N CONDENSADORES CUANDO SE APLICA UNA TENSION DE CARGA AL NODO DE SALIDA. TRAS LA TRANSFERENCIA DE DATOS A LOS CONDENSADORES PONDERADOS EN BINARIO, SE PRECARGAN LOS TRANSISTORES DE CONMUTACION Y TRAS ESTO LOS N CONDENSADORES SE CONECTAN EN PARALELO PARA PRODUCIR UNA TENSION ANALOGICA CORRESPONDIENTE A LOS DATOS EN SERIE.
