A JFET biased junctions

  1. Aug 3, 2017 #1
    I have a understanding problem with the JFET Transistor. I need this for the exam.
    Gate-Source Voltage = 0V.
    How are the PN Junction biased between Drain and Gate and Gate and Drain.
    For the following cases.
    Vds = 0V this sould be the thermal equilibrium
    Vds < Vdsat (both reverse ?)
    Vds > Vdsat (both reverse ?)

    The exercise is i have to draw the bandstrucutre at source contact and in the pinched off region at the drain contact.
