Abstract
LA COLOCACION DE LA CONEXION DISPONE DE UN DISPOSITIVO TRIGGER-SCHMITT DE ALTA AMPLIFICACION (16) CON DOS AMPLIFICADORES DE DIFERENCIA (I, II) ACOPLADOS AL DORSO Y TRANSISTORES BIPOLARES (T1, T2, T1'', T2''). PARA REDUCIR LA FRECUENCIA DE ESQUINA DEL DISPOSITIVO SCHMITT (16), EXISTE AL MENOS UN CONDENSADOR ADICIONAL (C1, C3, C5, C7; C2, C4, C6, C8) EN CADA AMPLIFICADOR DE DIFERENCIA (I, II), POR LO CUAL SE AUMENTA LA CAPACIDAD DE ENTRADA DE CADA AMPLIFICADOR DE DIFERENCIA (I,II) Y EL DISPOSITIVO SCHMITT (16) RECIBE UNA CARACTERISTICA DE PASO PROFUNDO.
