A current stabilizer equipped with field-effect transistors of the enhancement type has two parallel current paths which are coupled by means of two different current coupling circuits in order to obtain a stabilizing point. At least one of the two coupling circuits comprises two field-effect transistors which are each included in one of the two current paths. One of said field-effect transistors has a gate-source voltage which is a constant fraction of the gate-source voltage of the other transistor. This is achieved by including in series with said one transistor, a third field-effect transistor with interconnected gate and drain electrodes so that the other one of said two transistors has a gate-source voltage which is twice as high as that of the said one transistor. The other current coupling circuit is of the opposite conductivity type and may be a current mirror, but it may also comprise the complementary version of the one current coupling circuit.
