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

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
