Abstract
A method includes generation of a first current proportional to absolute temperature and formation of a second current representative of the temperature variation of the threshold voltages of the transistors of the inverter and limited to a fraction of the first current. This fraction is less than one. The inverter is supplied with a supply current equal to the first current minus the limited second current.
