Homework Help: About the MOSFET

  1. Oct 20, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    How current flows through n channel mosfet since bassicaly by applying positive voltage to the drain and negative to the substrate we actualy make the depletion layer grow widher. I mean when there is positive voltage at the gate it attracts electrons and thus creating a layer underneath the gate and between S and D that is depleted of mobile charges. And the drain is also reverse biased.

    3. The attempt at a solution
    Is there some kind of drift current from S to D like in the bjts?
