When I work with differential pairs, I constantly deal with the following transistor construction, for two cut transistors:
AB|BA
BA|AB
But for better matching, I think this one below would be better, giving 2 axis of simmetry, mirroring the x-axis and the y-axis:
AB|AB
-----
BA|BA
Where am I wrong?? Why is the first used more than the second?
AB|BA
