Abstract
The invention concerns a switching circuit () adapted to generate a pulse when there occurs a rising edge of a signal applied on an input terminal (CTRL), comprising: a first NPN type bipolar transistor (TN) whereof the transmitter is connected to the input terminal; a second transistor (TP) whereof a control electrode is connected, through a first resistor (Re), to the input terminal, the base of the first transistor being connected to a supply potential (VDD) by the second transistor in series with a second resistor (Rp); and a third transistor (TN) connecting an output terminal () of the switching circuit to a reference potential (GND) and whereof a control electrode is connected to the collector of the first transistor (TN).
