Arrangement for measuring at least one value of a voltage applied to an electronic component

A method for measuring at least one value of a signal flank occurring at an electronic component with an arrangement comprising a first signal transmitter (14) for emitting a first switching signal (28), the first signal transmitter (14) being coupled to a first switch (2) that is controllable by the first switching signal (28), the electronic component (1) being connected in series to the first switch (2) which is connectable, via the electronic component (1), to an electric energy source (3), a second signal transmitter (17) for emitting a second switching signal (32), a second switch (11) being coupled to the second signal transmitter (17), and being controllable by the second switching signal (32), a capacitive accumulator (10) being connected in series with the second switch (11) and being connectable in parallel, via the second switch (11), to one of the electronic component (1) and to the series connection formed by the electronic component (1) and the first switch (2), and an analog/digital converter (12) being connected in parallel to the capacitive accumulator (10), the method comprising the steps of:

• a) at least one of applying a voltage and supplying a current to the electronic component (1) at a first switching time (t1);
• b) connecting the capacitive accumulator (10) in parallel to the electronic component (1);
• c) separating the capacitive accumulator (10) from the electronic component (1) at a second measuring time (t3), and the second measuring time (t3) being set back by a time difference behind a first measuring time (t2);
• and
• d) recording and digitizing the voltage applied to the capacitive accumulator (10) at the second measuring time (t3).

An arrangement for measuring at least one value of a voltage applied to an electronic component, the arrangement comprising:

• a first signal transmitter (14) being connected to a first switch (2) which is connected in series to the electronic component (1) that is connected to an electric energy source (3),
• the first signal transmitter (14) transmitting a first switching signal (28) to the first switch (2), the first switch (2) either opening or closing depending on the first switching signal (28) transmitted by the first signal transmitter (14) to either facilitate or disrupt communication between the electronic component (1) and a ground (13);
• a second signal transmitter (17) being connected to a second switch (11), the second switch (11) being controlled by a second switching signal (32) that is transmitted by the second signal transmitter (17);
• a capacitive accumulator (10) being connected in series to the second switch (11), and connectable in parallel, via the second switch (11), to either the electronic component (1), or the series connection formed by the electronic component (1) and the first switch (2);
• and
• an analog/digital converter (12) being connected in parallel to the capacitive accumulator (10).
