Hi friends
As you know, there is 2 types of CMFB, one for continuous time and the other for switch capacitor(for switch capacitor application).
which one is good for OPAMP of stages?

Hi every body
i got some nice notes for designing folded cascode OPAMP with CMFB switch capacitor
i hope are useful for every one
many thanks
 

Well, as far as I know,continuous CMFB can not be used in SC circuits because switch will induce high frequence noise which continuous CMFB can not deal with.

I think what you said is not correctly true. there have been papers about sc circuits using continuous time cmfb.
 

in circuit design, it is easier to use SC CMFB,
but maybe in the layout or fabrication, continuous one is easier

continouse cmfb in better than sc cmfb in folded cascode amplifier.

may you explain it, thanks!
 

Here is a free circuit of OPAMP with CMFB for us to download :

**broken link removed**
 

continuse have large area than sc part
 

That's really useful article, thanks

Can anyone find a good website about ADC? I think Ken Martin's book is especially useful to those who are very beginner ofADC

Here is a really good website covering all the subject of Analog

can anyone send me some paper abt pipelined ADC
