An analytical model is presented for the 3D subthreshold electrostatics of low-doped gate-all-around MOSFETs with circular and square cross sections. The model is based on a solution of the 3D Laplace equation utilizing the high symmetry of the devices and assuming near-parabolic potential distributions in the directions perpendicular to the gates for the central regions. To account for short-channel effects, additional functional forms are used near source and drain. High precision is made… CONTINUE READING
