[sandhaajith]

can anyone explain the gm vs id method of designing.
pls post any relevant materials in the above topic

These documents will help you definitly...

[sandhaajith]

any book reference?i have these two.
thanks for the trouble anyways...ashish

 

[ashish_chauhan]

you can refer to analog design by LAKER and SANSEN... this book is present in this forum.

But I cannot say how detailed is the discussion they provide.

by the way if u get some thing interesting and worth reading please notify me too!!

thanks!!

hi.mebbe this is of help

 

[ashish_chauhan]

thanx dear ... but I use hspice and dont have much problem plotting the curves.

but to me the methodology it self is not very clear.

thx your.

stanford ee214 notes show this method in detail.

i need it now, thanks a lot, very good!gm and i-v curve is very usefull in ana design...

stanford ee214 notes show this method in detail.

They are really good... You can have the handouts directly from the stanford site..

From what I read about gm/Id methodology, I thought we will chart all spec as a function of (gm/Id), which can be associated with Inversion Coeff. However, EE214 notes also chart fundamental "figure of merits" as a function of Vov (over drive voltage), which I thought we want to avoid doing so. Can anyone shed some light?

Thanks,

@ hdmi
- Vov (overdrive voltage) can be seen as useful parameter only in the region of strong inversion. In moderate inversion are the equations with Vov (the most of them, at least) not applicable.
- gm/Id methodology, on the other hand, applies not only for strong inversion, but also for moderate inversion and weak inversion.
