Abstract
(DE)
Die Erfindung betrifft eine Begrenzerschaltung mit einem Signaleingang (E1) und einem Signalausgang (A) zur Begrenzung eines am Signalausgang (A) anliegenden, einer mit dem Ausgang der Begrenzerschaltung verbundenen weiteren Schaltung (SCH) zuführbaren Ausgangsssignals, ein Spannungsanschluss (E2) zur Zuführung einer Vorspannung (U) sowie ein Transistor (T) vorhanden ist, wobei der Gate-Anschluss (G) des Transistors (T) über eine erste Anpassschaltung (A1) mit dem Spannungsanschluss (E2) und über eine zweite Anpassschaltung (A2) mit dem Signaleingang (E1) verbunden ist.
(EN)
The invention relates to a limiting circuit having a signal input (E1) and a signal output (A) for limiting an output signal that is present at the signal output (A) and that can be fed to a further circuit (SCH) connected to the output of the limiting circuit, wherein a voltage connection (E2) for feeding a bias voltage (U) and a transistor (T) are present, wherein the gate connection (G) of the transistor (T) is connected to the voltage connection (E2) by means of a first matching circuit (A1) and to the signal input (E1) by means of a second matching circuit (A2).
(FR)
L'invention concerne un circuit limiteur, comprenant une entrée de signal (E1) et une sortie de signal (A), pour la limitation d'un signal de sortie appliqué à une sortie de signal (A), pouvant être acheminé à un autre circuit (SCH) connecté avec la sortie du circuit limiteur, cependant qu'il est prévu une connexion de tension (E2) pour l'alimentation d'une tension préalable (U), et un transistor (T), la borne de grille (G) du transistor (T) étant connectée, via un premier circuit d'adaptation (A1), avec la connexion de tension (E2) et, via un second circuit d'adaptation (A2), avec l'entrée de signal (E1).
