  • Compensation device for compensating PVT variations of an analog and/or digital circuit
    Patent number: 11012067
    Abstract: A compensation device for compensating PVT variations of an analog and/or digital circuit. The compensation device includes a transistor having a first terminal, a second terminal, a third terminal, and a fourth terminal allowing to modify a threshold voltage of the transistor. The transistor is configured to be in saturation region. The voltage at the third terminal has a predetermined value and the difference between the voltage at the second terminal and the voltage at the third terminal has a predetermined value. A current generation module is configured to generate a current of a predetermined value. A compensation module is configured to force this current to flow between the first terminal and the third terminal by adjusting the voltage of the fourth terminal.
