The current measurements are calibrated to a common temperature using the following relationship: $$I_{temp}^{SF} = \left ( \frac{T_{ref}}{T_{meas}} \right )^{2} \times e^{eE_{g}^{Si} \frac{T_{ref}-T_{meas}}{2 k_{B} T_{ref} T_{meas} }} $$ where $ T_{ref} $ is the reference temperature, $ T_{meas} $ is the temperatured measured during the test, $ e $ is the electric charge, $ E_{g}^{Si} $ is the band gap energy of silicon, and $ k_{B} $ is the Boltzman constant
