  Excellent tutorials as usual... <br><br>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?

  One thing you havent mentioned is what frequency this amplifier is intended to work at.<br>You have 100nF capacitors..which have reactance of 1.5k at khz <br>159 ohms at 10khz<br>And 15.9 ohms at 100khz <br>So it looks like this is really well above 100 khz ?

  On option 2 how does the capacitor reflect to the base when it&apos;s not polarized?

  Thank you for demonstration .I have a question please.When the matching impedance become necessary and when it is not? For your first circuit ,you achieve impedance matching between in output , while in input side the matching is missed

  Where did 26 come from.

  Input coupling cap goes to the left or right of the bias divider?

  Prof Aaron Danner, I have been following your work since Playlist #1, which included 30 other Videos for Calculation Transistor Gain. I find it quite frustrating that each time you explain the Common Emitter Configuration, you present a revised method and a much larger equation for calculating the AC gain. Could you clarify why you are not consistent? I am getting very confused with the numerous changes in your approach to calculating AC gain. Which method is most Accurate? Could you delete some of the videos with different, shorter equations and explanations? I have prepared so many pages of notes about AC Gain Calculation for CE Amplifier, and this specific Video includes more variables that previous videos did not include. So it means trash those notes or discard this video??

  Why are other characteristics of the transistor not taken into account in the calculation, such as the volumetric resistance of the base and collector?
