Razavi Electronics2 Lec22: Dominant-Pole Approx., Resp. of CE/CS & Common-Base/Gate Stage

[@enesog]

at 14:11 wp2 = wp1 / (wp1*wp2)
In between the two terms of wp2 there is a division operator instead of a multiplication.

[@animeshgautam6197]

i was also thinking same :))

[@srijanisallyouneed]

Yeah

[@zinhaboussi]

true

[@hatsuki23.11]

@@zinhaboussi yeah, i think same

Thank you, Professor Razavi, for the incredible lecture. It was extremely informative, and we’re hopeful that there will be an advanced course in the near future.

nothing to do ?

[@mnada72]

Waiting eagerly for circuit theory I & II and the rest of the series.

[@muratt6894]

Thank you

[@hardikjain-brb]

16:00 By miller since Av^-1 is 0 we can take CDB to ground and get CDB*RD

[@amitgalkin1215]

thank you!

at @2:05 shouldnt it be Vout/Vin instead of Vin/Vout?

[@srijanisallyouneed]

43:42 *Isn't Gain now = 2GmRc and BW = 2/RcCl

[@ranjanyadav9011]

gm->2gm but Rc->Rc/2 so gain remains same it is the BW which doubles

[@vedantbansal4471]

31:11 wouldn't Cox also be doubled so effectively gm ---> 2gm?

[@naveenkandi3862]

Cox is capacitance per unit area so it doesn't depend on width and length of the MOSFET

[@taylorlangley900]

There is like 400 ads in this video

[@mitrobge]

Vin/Vout to be reversed
