Dear friends,
I have question about the common centroed matched array. I have this array for example to match two transistors A and B
ABBA
BAAB
ABBA
BAAB
or I can make it
ABBA
BAAB
for sure the first array is supposed to be the best but during work I see it is consuming a lot of wiring which I think it will add considerable parasatics.
The second array is working fair but it has a problem with big transistors in which dividing them by 4 is not enough. Therefore I have two options in which I want to take your opinion on
the first is extending the array horizontally like this way
ABBA ABBA
BAAB BAAB
or I keep using the
ABBA
BAAB but using two gate per unit transistor in the array
Which one you think it match better ?
Thank you in advance
