plz make your question more clear.what do you mean?
in my opinion,there is no tight relation between the ESD and latch up.
ESD is to protect the core;Latch-up is because of the parasitic effect of the transistors.
Re: Dummy Transistor
The dummy transisitor is used for the purpose of transistor matching and guarding,especially in differential amplifier,it include not only the dummy poly,but also the dummy diffusion.
the dummy poly is used for the purpose of lithography in the process,to ease the problem...
My opinion is that analog will change but it still has a good future.For our students and engineers,we must prepare for these changs such as quatum and molecular electronics.
Re: adc converter design
You'd better study some classes and reading several books and papers
on AD/DA design.youmay find these in download session in this forum.
psub2 layer
yes ,it is a virtual layer only exsited in EDA tools to satify aome rules and for the purpose of convinience,used for LVS,etc.In maufacturing , it does't exist,so you can't use it for any real application.
Re: DFM
In lithography ,the illumination source wave length is 193nm ,but the feture size is 90nm,65nm or 45nm,the phsycical dicrimination limite is 1/2 wavelength,so diffration,and intrference occure,the transfered pattern may be distorted even vanished on the wafer when projecting,so...
