J.F. Mogniotte, C. Raynaud, M. Lazar and L. Michel Analytical modelling of a lateral dual gate MESFET for integrated circuit in SiC
ABSTRACT: This paper presents a static analytical model derived from a lateral dual gate MESFET in SiC for which the gates have the particularity to be of different physical nature: the first gate is a Schottky barrier and the second gate is a bipolar junction. In order to build a design-kit dedicated to simulation, a spice model has been developed that includes an analytical model of the MESFET which takes into account especially the influence of the both gates on the channel conductivity. The model provides results with a good agreement with experimental measurements and continuous optimization processes allow having a better matching.KEYWORDS: SiC, analytical model, MESFETRead full text (pdf)
