Hi all
my bgr was taped out but output(1.25V) is higher than simulation result(1.185V).
I doubt amp's offset causes this problem so I do simulation like following condition.
the output voltage of bgr =1.25V when i add a vdc=5mV between the AMP input node d1 and E of biplor. In this case the difference voltage of d1 and d2 is <1mV.
Any one can tell me can I decide the offset results in this higher output problem?
And how to fix it ? Thanks.
