Similarly, in field effect transistors, and MOSFETs in particular, refers to gate-source conductance.Transconductance is the change in the drain current when we have small change in the gate/source voltage.id = gm*vgs. gmb: refers to transconductance which … WebJul 13, 2024 · The voltage between the base and the emitter is apparently called "thermal voltage" and at room temperature it is approximately 26 m V. This voltage divided by the bias current gives the resistance r π. But normally in circuit analysis it is assumed that a transistors base-emitter junction has the voltage of a diode, approximately 0.7 V across it.
