switched capacitor noise pss pnoise
The following is the detail about previous question.
My circuit is a quite typical folded cascode amplifier
with pmos input. There are two AUX amplifiers working as gain booster
on cascode NMOS and PMOS, respectively.
There are several questions I want...
spectre pss pnoise
I have run a PSS/Pnoise analysis for my sampling & hold circuit. The
structure of circuit is switched capacitor, flip around with a
gain-boosted amplifier. When printing noise summary, I found the top 8
noise contributers (they generated 70% of total noise) are not from...

main amplifier, but...
This confused me and which is not correct in the current feedback system?
My opinion is that the 3db bandwidth of close loop system is BW/As.(Bw is the unit gain bandwidth of open loop system and As is the Gain of close loop system)
Re: Question about buffer
thank u for your help.
we can use clear supply for simulation so the noise in the supply will not be calculated.
but i want to know which order of the bandwidth is needed in the case.
In the application this buffer must drive out a big capacitance so i want to design...
