    Field Effect Transistor - High Input Impedance

    What about JFET? There is no such insulating layer between the gate and the channel.. Then?

    Field Effect Transistor - High Input Impedance

    I know FET offers a very high input impedance..but what's the reason behind it? Is it due to the reverse voltage applied at gate with respect to the source which makes the P-N junction reversed biased? If that the case, what happens when there is no voltage applied at gate?

    Field Effect Transistor - Minority Charge Carriers

    Unlike BJT, Why the minority charge carriers in FET do not participate in conduction? What is actually happening with the minority charge carriers?
