Abstract
A circuit for comparing a voltage with a threshold, including: first and second nodes of application of the voltage; a first branch including a first transistor series-connected with a first resistor between first and second nodes; a second branch parallel to the first branch, including second and third series-connected resistors forming a voltage dividing bridge between the first and second nodes, the midpoint of the dividing bridge being connected to a control node of the first transistor; and a third branch including a second transistor in series with a resistive and/or capacitive element, between the control node of the first transistor and the first or second node, a control node of the second transistor being connected to the junction point of the first transistor and of the first resistor.
