3.12.2 Non-Saturation Effect

Some devices do not exhibit prominent or abrupt velocity saturation. The parameters $A1$ and $A2$ are used to tune this non-saturation effect to improve the $I_{d,sat}$ or $g_{m,sat}$ fitting.

$T_0 = max \Bigg[ \Bigg( A1(T) + \dfrac{A2(T)}{q_{ia} + 2.0 \cdot \frac{nKT}{q}} \Bigg) \cdot \Delta q_i^2, -1 \Bigg] \qquad (3.391)$

$N_{sat} = \dfrac{1 + \sqrt{1 + T_0}}{2} \qquad (3.392)$

$D_{vsat} = D_{vsat} \cdot N_{sat} \qquad (3.393)$
