A current stabilizing arrangement includes a first and a second current circuit or path 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 these currents so as to enable a negative second-order temperature dependence to be compensated for in the case where the arrangement is used as a voltage or current reference source, the current stabilizing arrangement comprises a transistor whose base-emitter junction constitutes said second semiconductor junction, the base circuit of said transistor including a resistor. |
