Transconductance - University of Arizona
atlas.physics.arizona.eduTransconductance is a contraction of transfer conductance. The old unit of conductance, the mho (ohm spelled backwards), was replaced by the SI unit, the siemens, with the symbol S (1 siemens = 1 ampere per volt). Transresistance Transresistance, infrequently referred to as mutual resistance, is the dual of transconductance. The term is a

This leads to the equation, where, is the normalized constant that determines the maximum conductance when all the channels are open [5, 6].
