Abstract
(DE)
Es ist eine Gleichtaktbegrenzungsvorrichtung (60; 60 A; 60 B; 60 C) für einen Bus (40) eines Bussystems (1) und ein Verfahren zum Begrenzen von Gleichtaktstörungen in einem Bussystem (1) bereitgestellt. Die Gleichtaktbegrenzungsvorrichtung (60; 60 A; 60B; 60 C) hat mindestens einen Stromspiegel (64; 64A) der zwischen eine erste und eine zweite Busleitung (41; 42) des Busses (40) geschaltet ist, wobei der Stromspiegel (64; 64A) einen ersten Transistor (641; 6410) und einen zweiten Transistor (642; 6420) aufweist, deren Steueranschlüsse miteinander verbunden sind, und wobei mindestens zwei Anschlüsse des ersten und zweiten Transistors (641, 642; 6410; 6420) miteinander und mit Masse (43) verbunden sind.
(EN)
The invention relates to a common-mode limiting device (60; 60 A; 60 B; 60 C) for a bus (40) of a bus system (1) and to a method for limiting common-mode interferences in a bus system (1). The common-mode limiting device (60; 60 A; 60 B; 60 C) has at least one current mirror (64; 64A), which is connected between a first and a second bus line (41; 42) of the bus (40), wherein the current mirror (64; 64A) has a first transistor (641; 6410) and a second transistor (642; 6420), the control terminals of which are connected to one another, and wherein at least two terminals of the first and second transistor (641, 642; 6410; 6420) are connected to one another and to ground (43).

Dispositif de limitation en mode commun (60, 60A, 60B, 60C) pour un bus (40) d'un système de bus (1) et procédé de limitation de bruitage en mode commun dans un système de bus (1). Le dispositif de limitation en mode commun (60, 60A, 60B, 60C) comporte au moins un miroir de courant (64, 64A) monté entre une première et une deuxième ligne de bus (41, 42) du bus (40) et comportant un premier transistor (641, 6410) et un deuxième transistor (642, 6420), dont les bornes de commande sont reliées les une aux autres. Au moins deux bornes du premier et du deuxième transistor (641, 6410, 642, 6420) sont reliées les unes aux autres et à la masse (43).
