transconductance
- noun
- /trænskənˈdʌktəns/
- Specialized
- Understanding the transconductance helps in predicting how an electronic device will respond to input voltage changes.
Examples
-
The servo positioner is a power transconductance amplifier used to drive a voice-coil motor and integrate power-fault detection with built-in retraction circuitry.

Morphology
transconductance = conductance (semi-transparent) = trans + conduct + ance
Formed by prefixing 'trans-' to the technical noun 'conductance'; the morphological relation is regular but the precise technical sense is domain-specific.
Etymology
The word transconductance joins the part trans- meaning 'across', as in transport, with conductance, from conduct meaning 'to lead or carry', as in conductor. So transconductance is a measure of how much electrical current changes when the input voltage is changed.
