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
