Nous avons développé un modèle macro qui nous permet de décrire les caractéristiques précises du LDMOS DC/AC. La caractérisation de la capacité anormale d'entrée de grille est la question clé dans le développement du modèle LDMOS. Nous avons récemment utilisé un schéma RC distribué de type T pour la région de dérive LDMOS à chevauchement de porte. La résistance et la capacité dépendantes de la polarisation sont modélisées indépendamment dans Verilog-A en tant que modèle R et capacité PMOS. Le facteur de division du R distribué est introduit pour refléter l'effet de bouclier de la capacité de chevauchement de grille. La comparaison entre le nouveau modèle et les résultats de mesure a prouvé que le macro-modèle développé reproduit avec précision non seulement la capacité d'entrée de la grille, mais également les caractéristiques CC.

Abstract: We have developed a macro model, which allows us to describe precise LDMOS DC/AC characteristics. Characterization of anomalous gate input capacitance is the key issue in the LDMOS model development. We have newly employed a T-type distributed RC scheme for gate overlapped LDMOS drift region. The bias dependent resistance and capacitance are modeled independently in Verilog-A as R-model and PMOS-capacitance. The dividing factor of the distributed R is introduced to reflect the shield effect of the gate overlap capacitance. Comparison between the new model and measurement results has proven that the developed macro model reproduces accurately not only the gate input capacitance, but also DC characteristics.
