Hi prof!

Could please do more videos on Sedra Microelectronics? If you can cover 10 chapters it would be really helpful to ace the course! Thanks đź™‚

Hi Professor Tony

regarding the Analog IC Design textbook

do you provide any online course which covers the entire topics

of the textbook on any platform whether it is a free or paid course

thanks in advance

Besides the model files for MOSFET, is there any model file for BJT and diode? Thanks.

Here is a typical model for an NPN transistor:

.model QECL NPN(Is=0.26fA Bf=100 Br=1 Tf=0.1ns Cje=1pF Cjc=1.5pF Va=100)

And here are models of a typical discrete NPN, PNP and diode:

.model Q2N3904 NPN(Is=6.734f Xti=3 Eg=1.11 Vaf=74.03 Bf=416.4 Ne=1.259

+ Ise=6.734f Ikf=66.78m Xtb=1.5 Br=.7371 Nc=2 Isc=0 Ikr=0 Rc=1

+ Cjc=3.638p Mjc=.3085 Vjc=.75 Fc=.5 Cje=4.493p Mje=.2593 Vje=.75

+ Tr=239.5n Tf=301.2p Itf=.4 Vtf=4 Xtf=2 Rb=10)

.model Q2N3906 PNP(Is=1.41f Xti=3 Eg=1.11 Vaf=18.7 Bf=180.7 Ne=1.5 Ise=0

+ Ikf=80m Xtb=1.5 Br=4.977 Nc=2 Isc=0 Ikr=0 Rc=2.5 Cjc=9.728p

Hi,

My professor is using one of the file here for an LTSpice assignment that is worth 40% of my final mark.

I need help adding 0.35 um CMOS file to LTSpice to use and simulate with. Any advice how to import?

I have tried adding to the directory but I have an error. I also tried the spice directive .op, but I don’t understand why there are three files _ss, _ff and _tt …etc.

Use the “.include” directive, pointing to the model file(s). Good luck!

Hello

How can I access to solutions manual?

thanks.

The solution manual is for active instructors only. Thanks for your interest.

Hi,

In chapter 6 (Basic Op-Amp Design and Compensation) on Page no. 252, you say slew-rate(SR) can be increased by increasing Veff.

But increasing Veff by some ratio, also decreases unity gain frequency(Wta) by same ratio, making SR independent of Veff.

Since SR = Veff*Wta.

Can you clarify, Please.

The key point is the assumption that the two-stage opamp is â€śproperly compensatedâ€ť as it says near the bottom of page 252. As you say, increasing Veff with constant bias current reduces the unity-gain frequency. Therefore, the compensation capacitor size can also be reduced while maintaining the same phase margin. This reduction in Cc provides an attendant improvement in slew rate.

Hi,Professors. Recently I am read the great book ” Analog integrated circuit design 2nd”, but I have a question about the sentence below( in page 180 of chapter4)

“This assumes rin<= or >>Rs, could you help me please.

Assuming r

_{in}<< R_{s}means that R_{s}may be neglected in (4.162> and the time constant is approximately r_{in}C_{gs}. Then, a further assumption is made that r_{in}is approximately 1/g_{m}to arrive at the final expression in (4.162).
