Kindly could you suggest me please how to match five equal MOS transistors (A,B,C,D,E) to have a good matching.
my idea is to devide each transistor in to five fingers.
Hello Senan ;-)
you probably meant ... into five multiple transistors? If you really want full common centroid, you have to use an even number. In this case you can create a 6x6 array, from which you dismiss one of the transistors as dummy (e.g. F).
ABCDEF
BCDEFA
CDEFAB
BAFEDC
AFEDCB
FEDCBA
This will also result in the most possible complex routing :-(
Hello erikl
kindly, could you please suggest me the case where it is just five and satisfying the full centroid . because five transistors with five fingers are also lead to square arra [5*5], why the even is the condition of full symmetry ????
