3.11.2 Output Conductance Due to DIBL

$PVAGfactor = \begin{cases} 1 + PVAG_i \cdot \dfrac{q_{ia}}{E_{sat} L_{eff}} &\text{for } PVAG_i > 0 \\ \dfrac{1}{1 - PVAG_i \cdot \frac{q_{ia}}{E_{sat} L_{eff}}} &\text{for } PVAG_i \le 0 \end{cases} \qquad (3.384)$

$\theta_{rout} = \dfrac{0.5 \cdot PDIBL1_a}{cosh \Big( DROUT_i \cdot \frac{L_{eff}}{\lambda} \Big) - 1} + PDIBL2_i \qquad (3.385)$

$V_{ADIBL} = \dfrac{q_{ia} + 2kT/q}{\theta_{rout}} \cdot \Bigg( 1 - \dfrac{V_{dsat}}{V_{dsat} + q_{ia} + 2kT/q} \Bigg) \cdot PVAGfactor \qquad (3.386)$

$M_{oc} = \Bigg( 1 + \dfrac{V_{ds} - V_{dseff}}{V_{ADIBL}} \Bigg) \cdot M_{clm} \qquad (3.387)$

$M_{oc}$ is multiplied to $I_{ds}$ in the final drain current expression.
