Current stabilizer comprising enhancement field-effect transistors

A current stabiliser comprising first and second parallel current paths current-coupled to each other via first and second current coupling circuits which define a different relationship between the currents in the first and the second current paths and with a common value unequal to zero at which the currents in the first and second path stabilize themselves, the first current coupling circuit comprising enhancement type field-effect transistors of a first channel conductivity type and the second current coupling circuit comprising a first enhancement field-effect transistor of a second channel conductivity type opposite to the first one and having a channel included in the first current path and a second enhancement field-effect transistor of said second conductivity type and having a channel included in the second current path, of which first and second field-effect transistors the source electrodes are coupled to a first common terminal, and means for defining a substantially constant difference between the gate-source voltage of the first field-effect transistor and the gate-source voltage of the second field-effect transistor.
