Hello everyone,
I designed an opmap in schematic view in Cadence. It is giving no offset.
Then I did the layout for the same, and I get an offset of ~20mV between the differential output nodes.
Can anyone suggest me the way to do away with it? Or is there any circuit which when augmented with the present circuit cancels the offset.??
Any paper/book/reference is welcome...
