exercise

In this exercise I'm given the Vd and Id in two operation points and I need to calculate Io and n from the Shockley equation. I've tried isolating Io and replacing it in the other equation but then I wasn't able to solve the n. Maybe I need to apply other strategy?

  • Hey @G36 thank you for your answer. How do I get the nV_T equation? – Gabriel Corrales Jun 19 '23 at 16:10
  • First, we need to rearrange the Shockley equation to get \$V_{F}\$ And next you need to find \$V_{F2} - V_{F1}\$. After that, you will be able to solve for \$nV_T\$ – G36 Jun 19 '23 at 16:36
  • Take a look at this example https://electronics.stackexchange.com/questions/502204/emitter-follower-class-a-amplifier/502218#502218 and \$ΔV_{BE}\$ equation. – G36 Jun 19 '23 at 16:40
  • @GabrielCorrales Usually need at least three. There is also a bulk resistance to pick up. – periblepsis Jun 19 '23 at 20:29
