Thanks for pointing this out. I think that Shockley is the original square law model, whereas Shichman-Hodges adds channel-length modulation and body effect to the original Shockley model. Indeed, Shichman-Hodges is the LEVEL-1 SPICE model, which would probably be the roughest you would go for analysis.
At 9:54, shouldn't the expression for drift current be: I_d = −v(x)⋅Q(x)⋅W since current is velocity times charge, and the charge is proportional to the width of the channel. I don't understand why the infinitesimal channel length dx is included. Can you please clarify this point?
Errata: At time @9:54 there shouldn't be a "dx" in the expression for current. Thanks to @arghya.7098 for pointing this out.
Great teaching! Really helped me with understanding velocity saturation.
Great to hear!
These courses are extremely helpful! Thank you so much.
Thanks!
Excellent excellent professor!!! Love the lectures
Thanks!
Excellent presentation, simple and to the point. Thanks a lot. Just one point: Square law model is Shockley or Shichman Hodges model?

Yes, you are right. There is an "extra" dx there. Thank you for pointing this out (it "magically" disappeared on the next slide ;)
@@AdiTeman Thank you for the clarification, Professor. I really enjoyed the lecture and appreciate your guidance on this point.
Will these courses be continued proffesor?
Yes. They will be uploaded soon.
