A SPICE simulation model for field emission triode

Abstract

In this work, a simple but accurate circuit model, which can be incorporated into circuit simulation programs such as SPICE, for field emission triode (FET) is developed. The model is based on the Fowler-Nordheim (F-N) J-E relationship but takes into account the charge distribution on the surface of the tip of the device. A procedure is also developed to extract the parameters of the model.
