Abstract: A circuit for shifting at least one input switching signal includes a CMOS bistable circuit having two branches, and a circuit for accelerating the switching of the bistable circuit. The circuit for accelerating the switching allows an output transistor of each branch to be switched to the off state when an input transistor of the branch switches to the on state. The circuit for accelerating switching includes, for at least one given branch, an associated current mirror generating a turn-off current for the output transistor of the branch on the basis of a turn-on current for the input transistor of the branch.
