¹⁷Assuming that $v_{D} > 120 mV$ (in forward), the element equation of the diode can be simplified to $i_{D} = I_{D 0} \cdot e^{\frac{q v_{D}}{kT}}$ . Then an increase of $I_{D 0}$ by a factor $N$ or zooming in on the curve by a factor $N$ gives the same result as left-shifting the exponential curve by $Δ v_{D} = \frac{kT}{q} \ln (N)$ . Numerically, $N = 10$ results in a left-shift by only $60 mV$ . $N = 100$ results in a shift of $120 mV$ .
