Abstract
In this generator a first current mirror (MP1, MP2) forms two circuit branches to be connected between supply terminals (V.sub.DD, V.sub.SS). Each of the branches includes transistors (MP1, MN1; MP2, MN2) which are series connected and have opposite conductivity types. A second current mirror (MP3, MN3) yields an image (i.sub.3) of the current (i1) flowing in one of the branches. An active component (MN4) forming a variable conductance is connected in series in this branch and is controlled in such a way that its value varies nonlinearly with the current image (i.sub.3). This conductance is thus traversed by a current whose intensity depends solely on the technological characteristics of the active component.
