    mosfet 2 questions????

    2)yeah I figured it out.it was because of the role of gate as a capacitor that in small signal is equal to open-circuit.thanx for ur help 1)in this condition Vgd is negative which shows that Drain does have more potential than Gate.but the main carriers are electrons so Drain will collect more...

    mosfet 2 questions????

    1)why in enhancement mosfet we say that if Vgs=0 and Vds is increasing the depletion area increases more around the Drain? 2)why we say (Ig=0) in enhancement mosfets?in Jfets it is clear but in E-mosfets we had two back2back diodes that Gate is located between them so the P-N junction is not in...
