Abstract
A device monitors at least one power switch which is series-mounted with a logic core between a first and a second potential. A connection point between the switch and logic core is carried to a third potential. The switch is biased by a biasing potential. The device includes a feedback control module mounted between first and second potentials which is capable of generating a set potential representative of the third potential variation. A biasing module of the power switch is mounted between the first and second potentials, and generates a biasing potential based on the set potential. The biasing potential linearly varies with the decrease of the third potential.
