A simple empirical circuit model, which can be incorporated into circuit simulation programs such as SPICE for a field emission triode is developed. The model is based on the Fowler-Nordheim (FN) J-E relationship but takes into account the space charge effect and the exponential-like charge distribution on the surface of the tip of the device. A procedure is also developed to extract the parameters of the model.
