Abstract
A delay generator comprises at least one programmable resistor Rmade of a chalcogenide-based phase-change material, said resistor Rbeing initialized, so as to generate a delay, in a way such that the resistance of the resistor Requals a pre-set initial value Rand such that the chalcogenide is in the amorphous phase, and a comparator comparing a reference electrical quantity that is stable over time with a variable electrical quantity representative of the resistance of the programmable resistor R, the comparator generating a singularity signal s, said singularity being generated when the difference between the two electrical quantities changes sign.
