Abstract
A PVT detection circuit including: first and second transistors of a first conduction type each having its control node coupled to a control line, the first and second transistors being configured such that the variations in their threshold voltages as a function of temperature and/or process are different from each other; and an amplifier coupled to a second main conducting node of each of the first and second transistors and configured to amplify a difference in the currents conducted by the first and second transistors in order to generate an output signal.

A PVT detection circuit comprising:
- first and second transistors of a first conduction type each having its control node coupled to a control line and a first of its main conducting nodes coupled to a first voltage rail, wherein the first and second transistors are configured such that the variations in their threshold voltages as a function of temperature and/or process are different from each other;
- and
- an amplifier coupled to a second main conducting node of each of the first and second transistors and configured to amplify a difference in the currents conducted by the first and second transistors in order to generate an output signal at an output of the circuit.
A method for detecting a PVT point comprising:
- activating first and second transistors of a first conduction type via a control line coupled to control nodes of the first and second transistors, wherein each of the first and second transistors has a first of its main conducting nodes coupled to a first voltage rail, and wherein the first and second transistors are configured such that the variations in their threshold voltages as a function of temperature and/or process are different from each other;
- and
- amplifying a difference in the currents conducted by a second main conducting node of each of the first and second transistors in order to generate an output signal.
