I'm drawing common centroid layout of current mirror. I'm new to analog layout. On the left and right side of the 1st and the last column of Mos, I think I should put dummy.
Do I also need put dummy on the top and bottom of the top and bottom row of Mos?
(If source and drain is on the left and right side of Mos)
In cadence, edit Instance Properties, I can choose "Gate M1 contacts" : both. Which will make two gates above and below a single Mos. Do I need to put two gate in one Mos to increase symmetry?
Thanks a lot!
