Abstract: A device for controlling a voltage-controlled switch from a digital signal, comprising: a first means for providing the digital signal to the output terminal of the switch; a second means for biasing the switch control terminal to a level greater than the threshold voltage of the switch and smaller than the sum of said threshold voltage and of the maximum voltage of the digital signal; and a third means for adding or subtracting to said level said maximum voltage of the digital signal respectively at the rising and falling edges of the logic inverse of the digital signal.
