transconductance (plural transconductances)
(electronics) The ratio of the change in output current to the change in input voltage across a circuit
As channel lengths are reduced without proportional reduction in drain voltage, raising the electric field in the channel, the result is velocity saturation of the carriers, limiting the current and the transconductance. Source: Internet
Crystal Fire p. 278 The "transistor" (a combination of "transconductance" and "resistor") was 1/50 as large as the vacuum tubes it replaced in televisions and radios and allowed electrical devices to become more compact. Source: Internet
For vacuum tubes, transconductance or mutual conductance (gm) is defined as the change in the plate(anode)/cathode current divided by the corresponding change in the grid/cathode voltage, with a constant plate(anode)/cathode voltage. Source: Internet
Because of this exponential relationship, the BJT has a higher transconductance than the FET. Source: Internet
Valve electrometers Valve electrometers use a specialized vacuum tube (thermionic valve) with a very high gain ( transconductance ) and input resistance. Source: Internet
Both changes reduce the carrier mobility, and hence the transconductance. Source: Internet
