COMMON-MODE LIMITING DEVICE FOR A BUS OF A BUS SYSTEM, AND METHOD FOR LIMITING COMMON-MODE INTERFERENCES IN A BUS SYSTEM

摘要

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).
