Abstract
A chain of switches is connected between a first power supply line coupled to a first voltage and a second power supply line coupled to the sector. These switches are controllable by a control signal. The control signal is propagated from a first end of the first chain towards a second end of the first chain without control of the switches during this first propagation. The control signal is then propagated in the reverse direction from the second end towards the first end with a control of the switches during this second propagation starting from a group of at least one switch situated at the second end. There is a detection of the arrival of the control signal at the first end of the chain at the end of its propagation in the reverse direction.
