The nonlinear temperature error due to the curvature ($c(T-T_r)$) of the $V_{BE}$: (a) T represents the deviation of the measured temperature from its linear approximation at a reference temperature $\left(T_r\right)$; (b) the curvature term is expressed as a temperature, and plotted for $\eta =3.0$ (solid line) and $\eta =3.5$ (dashed line).
