Abstract

SE PRESENTA UNA INVENCION PARA UN CIRCUITO DE PREDISTORSION BASADO EN UN CUBER BALANCEADO, PARA PREDISTORSIONAR UNA SEÑAL DE ENTRADA (V{SUB,IN}), CONSTANDO DE UN CUADRADOR (11) PARA PRODUCIR UNA SEÑAL DE SEGUNDO ORDEN Y MEDIOS PARA LA DIVISION DE LA SEÑAL (10'',14'') PARA DIVISION DE LA SEÑAL DE ENTRADA Y DE LA SEÑAL DE SEGUNDO ORDEN DENTRO DE LAS SEÑALES DIFERENCIALES. PARA PRODUCIR UNA SEÑAL DE TERCER ORDEN, LA SEÑAL DE ENTRADA Y LA SEÑAL DE SEGUNDO ORDEN, SON MEZCLADAS EN MULTIPLICADORES (15, 16) Y LAS SEÑALES DE SALIDA DE LOS MULTIPLICADORES, SON COMBINADAS EN ORDEN A ELIMINAR COMPONENTES NO DESEADAS. DE ACUERDO CON LA INVENCION, EL CUADRADOR TAMBIEN INCLUYE UNA SEÑAL DIFERENCIAL MANEJANDO Y COMBINANDO MEDIOS (12, 13), AVENTAJANDO UN DOBLADOR DE FRECUENCIA EN CONTRAFASE, PARA PRODUCIR UNA SEÑAL DE SEGUNDO ORDEN UTILIZANDO SEÑALES DIFERENCIALES. LA FASE (17) Y AMPLIFICACION (18) DE LA SEÑAL DE TERCER ORDEN, ES AJUSTADA DE ACUERDO PARA PRODUCIR UNA SEÑAL DE COMPENSACION DE DISTORSION, Y LASEÑAL DE ENTRADA (V{SUB,IN}) Y LA SEÑAL DE COMPENSACION DE DISTORSION SON COMBINADAS (19) PARA PRODUCIR UNA SEÑAL DE SALIDA PREDISTORSIONADA (V{SUB,1}).
