Transconductance in High Frequency Response Amplifiers Formulas
Transconductance is the ratio of the change in current at the output terminal to the change in the voltage at the input terminal of an active device. And is denoted by g
m
. Transconductance is usually measured using the Millisiemens for Electric Conductance. Note that the value of Transconductance is always positive.
