Abstract
A circuit arrangement for deriving an output current from an input current, which output current is limited to a current range which is bounded by at least one limit value. It is possible to limit high-frequency currents by avoiding current distributions or saturation effects in that the circuit arrangement comprises a current combination element (1) for forming an at least substantially linear combination of the input current (IE), the output current (IA) and a fixed reference current (IR) and by at least a rectifier circuit (2) arranged in the current path of the input current (IE) and/or the output current (IA).
