Description

This component consists of a simple diode parallel with an ohmic resistance ($ R$). The current passing through this component is defined as a function of the voltage across the ports, i.e.,

$\displaystyle i = I_{ds} ( \exp^{v/V_t}- 1)+\frac{v}{R}$

where $ I_{ds}$ and $ V_t$ are the saturation current and the voltage equivalent of temperature, respectively. If the exponent $ v/V_t$ reaches a certain limit ($ Maxexp$), the diode characteristic becomes linear to avoid overflow.
