    Select Question Language :


    Consider the following statements about a MOSFET:

    1. A MOSFET for microwave application is fabricated from GaAs, owing to its higher electron mobility than silicon.
    2. A MOSFET has lower switching speed than BJT.
    3. A metal gate depletion mode Si PMOS has positive threshold voltage.
    4. A depletion mode Si NMOS can be fabricated by reducing substrate doping significantly.

    Options :-

    1. All are correct.
    2. Only 1, 3, 4 are correct.
    3. Only 2, 4 are correct.
