Hi all,
  In layout of transistors, center of mass of
transistors tend to affect the matching between
transistors, i.e, if they do not have same center of
mass. That is the reason common centroid layout is
used.=3D20
  Anybody can explain me whts center of mass and how
does it affect the match/miss-match between
transistors.

Thanks in advance,

Regards
Partha!
