To determine electrostatic potentials in silicon channel of undoped DG SOI MOSFET devices, a graphical approach is proposed. The method keeps close to experimental reality by taking into account flat band potential at reduced channel lengths up to 25 nm. This graphical method solves a transcendental equation of Poisson’s equation to obtain electrostatic potentials at center and surface of device as a function gate and drain bias voltages.
