| 摘要 |
The invention concerns a switching circuit (20) 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 (TN2) whereof the transmitter is connected to the input terminal; a second transistor (TP2) whereof a control electrode is connected, through a first resistor (Re2), 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 (Rp2); and a third transistor (TN3) connecting an output terminal (22) of the switching circuit to a reference potential (GND) and whereof a control electrode is connected to the collector of the first transistor (TN2). |
