Hiiii i m very new in layouting of analog ic's ? I have one book The art of analog layout by ALLEN HASTING but i m not getting more about the finger dividing of a large width transistor.
You can read the book "Modern component families and circuit block design" by Nihal Kularatna, which will clear all your doubts. Just try and let me know.
If you need more details, don't hesitate to contact me.
Let us consider we have one transitor with Width(w)=5u,Length(l)=2u,Fingers(f)=3, Multiplication(m)=4.
That means you have 4 transisitors with 3 fingers each and with the w=5u, l=2u for each finger.
If a transistor has 3 fingers then it means that its either S or D are merged and we need to connect the rest.
Any how the total widthof a transistor =w * f * m (w-width,f-fingers,m-multipliers)....
