Modeling "Dog Bone" Gate Geometry n-Channel MOSFETs

Accurately modeling the current-voltage characteristics of MOSFETs designed with irregular gate geometries is critical to developing hardened-by-design (HBD) circuits. In this paper, the "dog bone" (DB) irregular gate geometry is investigated. The most accurate model for determining the effective widths (W
_eff
) and lengths (L
_eff
) for a DB gate applies conformal mapping techniques, but less complex techniques are applicable.
