I want to simulate the relationship between the Vos (offset voltage of an amp.) and the Vout(output of the amp) while the amp working as a close loop circuit with gain of 5.
In order to model the offset voltage source, a common voltage source with +/- 30mV was utilized. Now I want the offset...

I want design a two stages fully diff-opamp. But in many textbooks，each stage needs a cmfb circuit for balancing.
maybe there are some two stage fully diff-opamp just using only one cmfb~!!
who has any information about it ?
thanks in advance~!!
I'm sorry.I have not figured out your meaning.
Tell me more details plz...
when y=1,just M3...M6 are on,and M1,2 are off ...then why in and clk cannot be translated by switch...?
In this circuit ,I want to get Y=0 when IN=1&clk=1.
CLK is a pulse with PW=20ns ,
At the begining,signal IN is low(IN=0),and Y=1 ,so M1 M2 off, M3~M6 on.
When signal IN convert to high(1),and Y=0 ,so M1 M2 on,M3~M6 off. In this case ,IN and CLK was disconnected, and the input terminals of nand...
ac analysis for sc with cmfb
I have designed a folded cascode fully diffrential OTA, and the SC-CMFB works well.
But when I use Hspice to do AC analysis, the open loop gain is so small
In the waveform,we can found that the Av(0) equal to -20db.
Someone told me that Hspice is not suitable for...
Actually,I don't know how to set the x-axis in log scale previously....
Maybe I have got the answer....Because I have not set the X-axis,the curve looks
not good at all....
Thanks!!
The figure in this attachment looks nice now.
