Abstract

CORRECCION PARA AMPLIFICADOR, CON DOS CIRCUITOS CORRECTORES (CS1,PM2,NM3/2,CS2,NM4,PM4/3) CADA UNO DE ELLOS CONECTADO EN PARALELO EN LA FASE FINAL (PM1,NM1) DEL AMPLIFICADOR CON UNA FASE DE ENTRADA DE AMPLIFICADOR DIFERENCIAL (A1), CON DOS AMPLIFICADORES DIFERENCIALES (A2/3) QUE FORMAN UNA FASE INTERMEDIA Y CON LA FASE FINAL FORMADA POR LA CONEXION EN SERIE DE UN TRANSISTOR PMOS (PM1) Y UN TRANSISTOR NMOS (NM1) CUYO PUNTO DE ENLACE (VOUT) VA CONECTADO AL ESTADIO DE ENTRADA A TRAVES DE UN CIRCUITO DE RETROALIMENTACION (FC). CADA CIRCUITO DE CORRECCION PUEDE MEDIR LA CORRIENTE CONTINUA (I1;I2) A TRAVES DE UN TRANSISTOR DE SALIDA (PM1,NM1) PARA COMPARAR UNA CORRIENTE CONTINUA DE MEDICION (I3;I4) OBTENIDA A PARTIR DE LA CORRIENTE CONTINUA MEDIDA CON REFERENCIA A UNA CORRIENTE CONTINUA (I5;I6) Y CAMBIAR EL VOLTAJE DE CORRIENTE CONTINUA EN LA COMPUERTA DEL OTRO TRANSISTOR DE SALIDA (NM1;PM1) EN FUNCION DE LA DIFERENCIA, GENERANDO ASI UNA FUNCION DE CORRECCION EN EL AMPLIFICADOR A TRAVES DEL CIRCUITO DE RETROALIMENTACION.
