Abstract

UN AMPLIFICADOR DE ESTADO SOLIDO MULTIETAPA (110) EMULA LA DISTORSION ASOCIADA CON EL FLUJO ACTUAL DE REJILLA EN UN AMPLIFICADOR DE TUBO MULTIETAPA (10) MEDIANTE UN DISPOSITIVO DE SUJECION (162, 164, 166) EN EL CIRCUITO ENTRE CADA ETAPA CONECTADA EN SERIE (112, 114, 116, 118). EN UNA REALIZACION PARTICULAR, CADA ETAPA (112, 114, 116, 118) COMPRENDE UN TRANSISTOR DE EFECTO DE CAMPO (FET) (112, 114, 116, 118) Y EL DISPOSITIVO DE SUJECION (162, 164 166) ES UN DIODO (172, 164, 166). EN OTRA REALIZACION, CADA ETAPA (112, 114, 116, 118) COMPRENDE UN PAR CONECTADO DARLINGTON DE TRANSISTORES (312A, 312B, 314A, ...318B). UN DIODO DE ENTRADA (374) Y UN CIRCUITO DE POLARIZACION MULTINIVEL (380) EMULA UNA ENTRADA DE CIRCUITO DE TUBO.
