[#186] The drain of an N-channel MOSFET is shorted to the gate such that V GS = V DS . The threshold voltage (V T ) of MOSFET is 1 volt. If the drain current (I D ) is 1 mA for V GS = 2 V, then for V GS = 3 V, the drain current I D is-
Correct Answer
(A) 4 mA

Correct Answer
(D) 65 kΩ
[#188] When a voltage divider biased amplifier has its Q-point near to the middle of the dc-load line, what is the maximum unclipped peak-to-peak output voltage?
Correct Answer
(D) 2V CEQ
[#189] The data sheet for a certain JFET ( Junction Field Effect Transistor) indicates that I DSS (drain to source current with gate shorted) = 15 mA and V GS(off) (Cut-off value of gate to source voltage) = -5V. What is the drain current for V GS = -2V?
Correct Answer
(D) 5.4 mA
