Hi manodipan,
Try solving for (V_A-V_BE)/R4 + (V_B-V_BE)/R5 such that this expression doesnt contain the second order Non-Linear Term (n-α)*ln(T/T₀) of eqn 5 of the paper...The VBE that i used in the expression is one generated with a constant current, so pls. dont substitute the normal expression for VBE in place of this.

Maybe this can help.
