- Start with the small signal model of a common emitter amplifier and derive a full and complete expression for the gain. Then, we will do it by inspection using impedance reflection. Then, let's work some example problems.

On option 2 how does the capacitor reflect to the base when it's not polarized?
Excellent tutorials as usual...
anyway, I think 26 in the intrinsic emitter resistance formula is kT/q. right? Thanks :)
Would you be able to confirm the accuracy of calculations on a specific example of a transistor in some circuit modeling program, for example in a Multisim?
Why are other characteristics of the transistor not taken into account in the calculation, such as the volumetric resistance of the base and collector?
It's a trade-off between complexity of the model and the utility gained from it.
@@adanner You explain the material well, I hope someday you will have a lesson on in-depth study of the properties of a transistor
