Abstract

In this paper, we present a unified compact model (Xsim) that is based on drift-diffusion/surface-potential (DD/SP) formalism for Si-bulk/SOI MOSFETs by incorporating a unified 2-dimensional electron gas (2DEG) model for extension to generic III-V MIS-HEMTs. The model has been validated with TCAD and experimental data for GaN-based HEMTs with nanometer gate lengths. Digital (inverter/ring-oscillator) and analog (cut-off frequency) circuit performance prediction based on nanometer GaN devices are also demonstrated. The ultimate goal is to develop a unified scalable model for III-V/Si co-integrated hybrid circuit design.
