Hi guys,

I have a doubt regarding the stick diagram of a cmos design. I want to design a single custom static CMOS gate (only one gate delay) that implements the function (NOT (A OR B OR C) AND D)). How to draw a MOS transistor schematic and a sticks diagram?

Thank you for the help.
 

You forgot a bracket. Schematic depends on where it will be.
 

I'm sorry. The function is NOT((A OR B OR C) AND D). Kindly help.
its urgent.

Thank you
 

Curious that you are concerned about gate delay but want to
work in terms of static design and a tall complicated gate
design. Elaborate tall stacks tend to have lousy drive strength
and drive symmetry. It's likely that when you add reasonable
wire and gate load, that a cascade of smaller combo gates
will give better performance (especially at the margins).

But the homework problem is what it is, I suppose.
