Summary: 
We have developed a compact double-gate metal-oxide-semiconductor field-effect transistor model for circuit simulation considering the volume inversion effect by solving the Poisson equation explicitly. It is verified that applied voltage dependence of the calculated potential values both at the surface and at the center of the silicon layer reproduce 2 dimensional device simulation results for any device structure, confirming the validity of the model for device optimization.
