$\eta = \begin{cases} \tfrac{1}{2} \cdot ETAMOB_t &\text{for } NMOS \\ \tfrac{1}{3} \cdot ETAMOB_t &\text{for } PMOS \end{cases} \qquad (3.345)$

$E_{effa} = 10^{-8} \cdot \Bigg( \dfrac{q_{ba} + \eta \cdot q_{ia2}}{\epsilon_{ratio} \cdot EOT} \Bigg) \qquad (3.346)$

$D_{mob} = \begin{cases} \text{If } BULKMOD = 0, \\ 1 + UA(T) \cdot (E_{effa})^{EU} + \dfrac{UD(T)}{\Bigg[ \dfrac{1}{2} \cdot \Bigg(1 + \dfrac{q_{ia2}}{0.01/C_{ox}} \Bigg) \Bigg]^{UCS(T)}} \\ \text{If } BULKMOD = 1, \\ 1 + (UA(T) + UC(T) \cdot V_{eseff}) \cdot (E_{effa})^{EU} + \dfrac{UD(T)}{\Bigg[ \dfrac{1}{2} \cdot \Bigg(1 + \dfrac{q_{ia2}}{0.01/C_{ox}} \Bigg) \Bigg]^{UCS(T)}} \end{cases}$

$D_{mob} = \dfrac{D_{mob}}{U0MULT} \qquad (3.348)$
