Offset votlage using transient

Hi guys, is it possible to measure the opamp offset voltage using transient analysis?

Can someone give me some tips on this?

Regards.

Hello yes its is possible.

Follow this guide:

Apply 2 transient ramps to the input:




you can keep other one constant this is easier:

Hi ata, thanks for the answer.

Those waveform doesn't look like transient analysis, I am sorry if it is. Can you explain better please?

Yes, you can. Yes, people do. But there are a couple
of things to watch out for. One is, the ramp time through
the linear window of the front end (that is, in the second
chart from ata_sa16, the region where the ouputs show
any non-flat-line quality, plus some) must be much less
than the delay time through the amplifier or you will
pick up an error term that roughly is dV/dt*prop_delay
and looks like Vio (but will flip sign if you flip ramp).

The other issue is, TRAN analysis error tolerances are
usually much looser than DC / OP tolerances and a
tiny bit of error residue at one spot in the amplifier
can make a big difference at another. Cranking down
the TRAN error tolerances will really blow out solution
time.

That said, TRAN is always a good thing to look at,
because it can expose other issues of behavior. Not
necessarily the most "accurate" simulation but often
a more realistic simulation of how the part works in
reality.

Its tran analysis. You keep one input constant and apply ramp to other one. You can also DC sweep.
