I believe that you meant Ic= α*Iref.Vbe1 = VBE (the Vbe associated with Ic=Iref, or, strictly speaking, Ic=Iref/α)
Well, I didn't know the specific number!You know that the collector current changes (at room temperature) by about 10x for every 60mV difference in Vbe voltage.
I typed what I meant, but what I meant was wrong.Thanks, it took me a while to understand the method but I get it now.
I believe that you meant Ic= α*Iref.
Why do you need an exact value for VBE? Does VBE appear anywhere in the final relationship between Vo and Vi?To find the exact value of VBE, I need to look at Vce-Ic characteristic in its datasheet?

Does it have in datasheet?
