Diode modelling
In electronics, diode modelling refers to the mathematical models used to approximate the actual behavior of real diodes to enable calculations and circuit analysis. A diode's I-V curve is nonlinear (it is well described by the Shockley diode law). This nonlinearity complicates calculations in circuits involving diodes so simpler models are often required.
This article discusses the modelling of p-n junction diodes, but the techniques may be generalized to other solid state diodes.
