Hello
I would have to understand how the MOSFET turn ON and turn off when I apply a command on its gate, my circuit seems to works well (I just want to apply a constant current on a load (simulated here by the diode) and the transistors are here to switch the current value.
The first capture represent the signal on the diode which is conform with my needs : a current step to a particular value, and another one.
here is the schematic :
**broken link removed**
**broken link removed**
The waveform2 is the signal on the Gate of the transistor M1 and the voltage of Vtest. On Vtest we can see a peak, why and how does it come from ?
**broken link removed**
I have peaks on the current in the diode and undershoot as you can see on the waveform3.
**broken link removed**
I hope that you could help me.
