Transconductance in Signal and IC Amplifiers Formulas
Transconductance is the change in the drain current divided by the small change in the gate/source voltage with a constant drain/source voltage. And is denoted by g
m
. Transconductance is usually measured using the Siemens for Electric Conductance. Note that the value of Transconductance is always positive.

FAQ
What is the Transconductance?
Transconductance is the change in the drain current divided by the small change in the gate/source voltage with a constant drain/source voltage. Transconductance is usually measured using the Siemens for Electric Conductance. Note that the value of Transconductance is always positive.
Can the Transconductance be negative?
No, the Transconductance, measured in Electric Conductance cannot be negative.
What unit is used to measure Transconductance?
Transconductance is usually measured using the Siemens[S] for Electric Conductance. Megasiemens[S], Millisiemens[S], Mho[S] are the few other units in which Transconductance can be measured.
