Transconductance in Low Frequency Response 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 negative.
