Subject: Correction to subtraction of IV curves

All -

When do my algebra, I get a result like the following for the "subtraction" of
two IV curves in the presence of non-equal bulk currents:

    Following Jon's nomenclature in his paper ... let Is be the transistor 
current.  Then

     -Is1 = Id1 - 2*Id2 + Ib1    Since it seems a good assumption is  that
Is2 is indeed zero and so Id2 = Ib2...

Seem like a reasonable correction term?  This is still not a very bad expression
to evaluate, as long as it seems right with the world.   Comments?

Thanks,
