Abstract :
We report the theory, implementation, and results of using a Poisson solver to compensate the measured values of drain conductance and transconductance in a nonlinear metal-semiconductor field-effect transistor so as to render them compatible with a large-signal model. The consequent restructuring of the I-V curves is exhibited
