Objective
this Should be a general description of what the term means, and then a description of transistor and vacuum tube properties.
probably copyrighted definitions:
General: Transconductance Transconductance is a property similar to both gain and conductance. When conductance is the will to generate an current for an apply voltage at to connecting points is the transconductance the will to generate an output current at the output connecting points for and applied input voltage at the input connecting points.
Specific applications: Transconductance Amplifier An amplifier which has an transconductance instead of ordinary voltage gain. Transconductance amplifiers can be of great use in some cursuits and is are better suited to drive certain loads (consider an speaker and the speaker cable). There exists transconductance amplifiers similar to operational amplifiers usually refered to as OTAs.
TRANSCONDUCTANCE—Transconductance is a ratio of the change in plate current to a change in grid voltage with the plate voltage held constant. Transconductance (gm) is usually expressed in micromhos or millimhos.
