Current stabilizer comprising enhancement field-effect transistors

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