Second, the proposed model includes Rds as a nonlinear resistance (depending on the gate-source voltage and the drain-source voltage), both in the off-state operation and in the on-state operation, including the nonlinear behaviour in the sub-threshold region, whereas conventional modelling of power MOSFETs normally includes the nonlinear capacitances only in the off-state operation.
This is because there is a direct resistive path from the drain terminal towards AC ground through the nonlinear resistance [R.
Note that the drain voltage has a DC bias value of 1 [micro]V because the nonlinear resistance [R.
A HIF model by using two series nonlinear resistance shown in Figure 3 was presented in 2001.
HIF model of Figure 5 including a nonlinear resistance two diodes and two DC sources with amplitudes which change in every half cycle randomly has been presented in 2004.
A nonlinear resistance controlled by EMTP models was introduced as an arc model in 2006 .
In this spirit, Comte and Marquie  pointed out that the introduction of the nonlinear resistance in the series branch of the nonlinear transmission line modeling the front propagation in reaction-diffusion equations can create a nonlinear diffusion and then the compactification of kink solitary waves.
Each cell contains in the series branch a linear inductor L shunted by a nonlinear resistance (NLR) and in the shunt branch the well-known bias-dependent capacitor C(V) responsible for the standard nonlinearity of the network.
In addition, experiments on KdV solitons performed in the NLTL under consideration, not presented here, exhibit an unstable behaviour until the nonlinear resistance parameter [gamma] is taken equal to zero.
But the secondary arc is modeled by a nonlinear resistance
