I think the title is pretty self-explanatory. For any FET or FET-like (MESFET, JFET, HEMT, etc) device, is Vd the same as Vds?
I was once told that they're not the same thing but I do not understand why. I would say that this has to do with the point of reference but to say that Vd is not the same as Vds then what is Vd referenced to? If we say that it is referenced to some other terminal, then it would become VdX where X is gate (Vdg), body (Vdb), source (Vds). Right?
Perhaps this is something which is only considered on the intrinsic level?
