Hi!
I need to plot transconductance(gm) of a MOSFET(NMOS) in LTSPICE. Any idea how to do it? I am using TSMC 0.18um technology file.
Also I need to observe gm upto 5 figures of precision. Please help me with that too...
Right now I can view gm using dc operating point (.op) and going to Menu Bar->View->Spice Error Log (screenshot attached)
and I can view gm for a single MOS upto only 2 decimal figures.
