I have a PMOS transistor circuit set up. These are my parameters: Vthreshold = -0.4 V Vgs = -3 V Vgt = Vgs - Vthreshold = -3 + 0.4 = -2.6 V Vds = Vgs - Vthreshold = -2.6V I'm trying to figure out what operating region this stupid thing is in. There are so many different ways of figuring this out, that it's getting very confusing -- it seems every source uses a different notation. I know it's not in the Cutoff region, because Vgs < Vthreshold. However, since Vds and Vgt are the same, how do I decide if it is in Linear or Saturation region? For linear: Vgs < Vthreshold and Vds > Vgt For saturation: Vgs < Vthreshold and Vds < Vgt This is really starting to bug me. If I could figure out how to find Vgd -- that is, voltage from gate to drain, I might be able to figure something out. However, my Vin = 2V and the drain is connected to a variable resistor and then to ground, I think Vgd = 2V. But I don't think this is possible since it's a PMOS, so I'm ignoring that parameter for now. Thank you.
