MOS W is not required to be greater than L.
One example of a large channel length is if you want to create a simple RC delay by using a MOS in triode/linear region. To create a increase the R, you would make the channel length longer.
For some reason, I can't attach the 2nd file... Is it too large? (It's only 2.6MB)
If you have IEEExplore, look up "Circuit Techniques for Reducing the Effects of Op-Amp Imperfections: Autozeroing, Correlated Double Sampling, and Chopper Stabilization" by Christian Enz, it was published I think...
op amp temperature dependent offset
I am working on something similar... These answers are based on my limited knowledge. Please feel free to add/comment on my input.
1. Offsets are worse in CMOS because :
(a) MOS Offset is a function of threshold mismatch, which does not occur in BJTs...
This question pertains to auto-zeroing offset in continuous time using a feed-forward topology.
I've read that for the nulling amplifier to read the main amplifier offset, the total system must be placed in a negative feedback. Why is this the case? How does it work?
Any comments/help would be...

I have 4 pole, 2 zero open-loop system. The phase margin is greater than 0 due to the placement of the zeros. However, there are points where the phase goes beyond -180 degrees due to the higher number of poles. Is this system stable when...
Hi, I was hoping someone could help me understand this problem.
Q: What is the max peak value of Vout in the following picture? and why?
** I believe it's supposed to be 2Vdd, but I don't know why.
