Hello , Below there is an implementation i got to the AD8277 differential to single ended concerter .
i noticed that the designer some times used 50mil on the top and 56mil traces on buttom.
near the chip the traces are much thinner (30 mil)
I know that one possible cause is current consumption but its not a high current circuit.
Why the traces varies in width threwout the layout?
Thanks.
