Transconductance in Amplifier Functions and Network 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 Siemens for Electric Conductance. Note that the value of Transconductance is always positive.
