More Information
Summary:The present invention concerns a compensation device for compensating PVT variations of an analog and/or digital circuit, said compensation device comprising: - a transistor comprising - a first terminal (D), - a second terminal (G), - a third terminal (S), and - a fourth terminal (B, G', G'') allowing to modify a threshold voltage (Vth) of the transistor, wherein the transistor is configured to be in saturation region, wherein the voltage at the third terminal (S) has a predetermined value, wherein the difference between the voltage at the second terminal (G) and the voltage at the third terminal (S) has a predetermined value, - a current generation module, configured to generate a current of a predetermined value, - a compensation module, configured to force this current to flow between the first terminal (D) and the third terminal (S) by adjusting the voltage of the fourth terminal (B, G', G'').
