WebJan 10, 2014 · 15. The body terminal is there whether we like it or not because of the construction of a MOSFET: The gate voltage modifies the channel width. But the gate potential is measured relative to the substrate potential, and the channel is formed in the substrate material. Therefore the MOSFET behavior depends strongly on the substrate … WebOct 13, 2024 · But to add to the confusion, there is another definition: gm=2*Id/(Vg-Vth) where Id is the drain current, Vg is the DC gate voltage, Vth is the threshold voltage. I found something like this to work a long time ago (might not be exactly that though) when i was not aware of that expression. It comes from a particular model for the MOSFET.
