Hi All

I wonder if you do have any material or introduction about finger
layout of cmos circuit?
For example

--------------------------
| --- --- --- |
| | | | | | | | <------Source
| --- --- --- |
| |
-------------------------------
|<---poly
-------------------------------|
| --- --- --- |
| | | | | | | | <---drain
| --- --- --- |
| |
-------------------------

I do not know how they are connected in circuit. I heard that the drain
and source can be interchanged.(What they mean by this?) I really cant
figure this out. I hope to understand this fully in circuit schematic
and also layout
Can you give me a good example how to understand this?
I will ask this in google group, hope you can answer there as well.
Thank you


rgds and thanks
Jason
