A current stabilizing arrangement with a first and a second current circuit in which currents with a mutually fixed ratio are maintained. These currents respectively flow through the series connection of a first semiconductor junction in series with a resistor and a second semiconductor junction. The voltage across the second semiconductor junction is maintained equal to the voltage across said series connection which results in currents, which are linearly dependent on the temperature. In order to add a component with a positive second-order temperature dependence to those currents so as to enable a negative second-order temperature dependence to be compensated for in the case of …
