The present disclosure relates to a method comprising: applying, by a control circuit, a first pulsed signal, consisting of sequential first voltage pulses, to the gate of a power transistor supplying a capacitive load of the circuit, the pulses of the first pulsed signal being separated from each other by a first wait time; further to one or more of the pulses of the first signal, making a comparison, by a comparator, of the value of the voltage across the capacitive load with a first voltage threshold value; and, if the first voltage threshold value is exceeded, applying a second pulsed signal, consisting of sequential second voltage pulses, to the gate of the power transistor, the pulses of the second pulsed signal being separated from each other by a second wait time shorter than the first wait time.

Method and circuit for power-up of an electronic circuit

A method for measuring radiation of energy photons, such as ultraviolet radiation, on a surface, may include programming at least one transistor by at least transmitting an electric charge to it. The method may further include measuring an electrical quantity of the at least one transistor receiving radiation of energy photons and estimating, based on this electrical quantity, an amount of radiation received.

Ultraviolet radiation measurement sensor

A method for designing masks adapted to the forming of integrated circuits, including the steps of: (a) forming a first test file including a set of configurations of integrated circuit elements; (b) forming a second test file comprising the elements of the first test file, less the elements corresponding to configurations forbidden by design rule manuals; (c) trans-forming the second test file by means of a set of logical operations implemented by computing means to obtain a mask file; (d) testing the mask file and, if the test is negative, modifying the design rule manuals; and (e) repeating steps (a) to (d) until the test of step (d) is positive.
