| Zusammenfassung: | An amplifier arrangement and a method for compensating for an offset in an amplifier is provided. A respective switch for connecting together the inputs in a compensation operating mode and for interrupting the feedback path in this operating mode is provided in an amplifier. A control device detects an output signal and drives a controllable current source, which can be coupled to one of the two inputs of the amplifier, in such a manner that a compensation current which minimizes the offset is provided. The arrangement and method can be used, for example, in transmission arrangements. |
