Abstract
The generator has an input stage (I) including a voltage divider for dividing the voltage between the power supply and the ground, having a node constituting the output of the input stage, and by a positive-feedback threshold loop, driven by another node of the voltage divider to make the voltage in the output node rise sharply when the voltage in the other node exceeds a threshold. A first Schmitt trigger (T1) is driven by the voltage rise front supplied by the input stage; and a former of output pulses (F) comprising a second Schmitt trigger (T2) is driven by circuit means adapted to directly apply to the second Schmitt trigger the voltage front arriving from the first Schmitt trigger and to restore the original voltage level with a preset delay.
