Abstract
A circuit includes, in series between a first terminal and a second terminal of application of a power supply voltage, and first and second branches. The first branch includes a first transistor and a first current source coupled to the first transistor. The second branch includes a resistive element, a second transistor coupled to the resistive element and forming a current mirror with the first transistor and a second current source coupled to the second transistor. The resistive element conditions a threshold of detection of a variation of the power supply voltage.
