Hi,
This is an two-stage opamp with miller compasation cap and Vdd=1.8v, Vss=0v.
I am measureing the input referred offset voltage (Vos) for this op-amp.
I bias DC=0.9v for both Vin+ and Vin- and AC=1 for the Vin+. Then, when Vin=0.9v, the Vout=0.912v, where both vout and vin are in the transition region(linear region) as shown in the attachment. So, the Vos=0.012v~~is it correct?
