  • Abstract
    A simple analytical model is proposed for the Fermi level as a function of the channel carrier density in a modulation doped FET (MODFET). It agrees well with numerical results including low carrier densities near the subthreshold region. The drain current is derived including drift and diffusion current, and the saturation drain current from the author´s model agrees well with experiment.
