Hey guys,
I'm getting started on LTPSICE and I'm trying to do a simple p chanel mosfet simulation.
For a reason I can't figure out it does not work the way I want it to.
You'll find the circuit in the attached pictures and the results of the two situations.
I have two scenarios :
1. N CHANNEL mosfet M2 is put on by the 5V source. The voltage of the gate of the P channel M1 is thus 12V, so the Vds voltage should be -12V. M1 should then conduct and the voltage at the output should be 24V.
2. N CHANNEL mosfet M2 is put off by the 5V source. The voltage of the gate of the P channel M1 is thus 24V, so the Vds voltage should be 0V. M1 should NOT conduct and the voltage at the output should be 24V.
I Can't figure out why but on the second scenario I still get 24V at the output.
Thanks a lot for the help guys !
