  1. For an P-channel enhancement type MOSFET determine the drain current if K = 0.278 x 10-3A/V2, VGS = -4V, VT = -2V, Voltage equivalent at 27°C = 26 mV.

    2. A.
    10 mA
    B.
    1.11 mA
    C.
    0.751 mA
    D.
    46.98 mA

    Answer : Option B

    Explanation :

    Drain current Id  = k (|Vgs| - |VT|)2

    = 0.278 x 10-3(4 - 2)2

    = 1.11 mA.
