Home/2.21 Use the model of Fig. 2.29 to sketch the transfer characteristic vO versus vId(vO ≡ v3 and vId ≡ v2 − v1) of an op amp having an open-loop dc gain A0 = 104 V/V, output saturation levels of ±10 V, and VOS of +5 mV. See Fig. E2.21. Observe that true to its name, the input offset voltage causes an offset in the voltage-transfer characteristic; rather than passing through the origin it is now shifted to the left by VOS.
