$I_{gc}$ is calculated only for $IGCMOD = 1$.

$A = \begin{cases} 4.97232 \times 10^{-7} &\text{for } NMOS \\ 3.42536 \times 10^{-7} &\text{for } PMOS \end{cases} \qquad (3.526)$

$B = \begin{cases} 7.45669 \times 10^{11} &\text{for } NMOS \\ 1.16645 \times 10^{12} &\text{for } PMOS \end{cases} \qquad (3.527)$

$T_0 = q_{ia} \cdot (V_{ge} - 0.5 \cdot V_{dsx} + 0.5 \cdot V_{es} + 0.5 \cdot V_{ed}) \qquad (3.528)$

$\begin{aligned} I_{gc0} &= W_{eff0} \cdot L_{eff} \cdot A \cdot T_{ox,ratio} \cdot I_{gtemp} \cdot NFIN_{total} \cdot T_0 \\ &\times exp \Big[ - B \cdot TOXG \cdot \Big( AIGC(T) - BIGC_i \cdot q_{ia} \Big) \cdot \Big( 1 + CIGC_i \cdot q_{ia} \Big) \Big] \end{aligned} \qquad (3.529)$

$V_{dseffx} = \sqrt{ {V_{dseff}}^2 + 0.01} - 0.1 \qquad (3.530)$

$I_{gcs} = I_{gc0} \cdot \dfrac{PIGCD_i \cdot V_{dseffx} + exp (PIGCD_i \cdot V_{dseffx}) - 1 + 10^{-4} }{ {PIGCD_i}^2 \cdot {V_{dseffx}}^2 + 2 \times 10^{-4}} \qquad (3.531)$

$I_{gcd} = I_{gc0} \cdot \dfrac{1 - (PIGCD_i \cdot V_{dseffx} + 1) \cdot exp (-PIGCD_i \cdot V_{dseffx}) + 1e^{-4} }{ {PIGCD_i}^2 \cdot {V_{dseffx}}^2 + 2 \times 10^{-4}} \qquad (3.532)$
