Recently I have question about why we should choose even number of finger.
As far as I know, the even finger is easier to layout in Current Mirror, Differential Pair when we need matching. (Because we should abut, place common centroid etc,...)
But I want to know how about in schematic view point. What is advantages of even number of finger?
I have searched and found out that there is more parasitic capacitance when drain is connected with dummy. But could you tell me more detail?
