Question 1

For the given transistor shown below, find V_S and V_D. (V_t = 2V,

Question 2

The enhancement type MOSFET in the circuit below operates according to the square law. μ_nC_ox = 100 μA/V², the threshold voltage (V_T) is 500 mV. Ignore channel length modulation. The output voltage V_out is

Question 3

For the MOSFET shown in the figure, the threshold voltage

and

The value of

(in mA) is ___________.

Question 4

What is the circuit diagram of clipper circuit for the transfer characteristic shown in fig?

Question 5

Two n-channel MOSFETs, T₁ and T₂, are identical in all respects except that the width of T₂ is double that of T₁. Both the transistors are biased in the saturation region of operation, but the gate overdrive voltage (V_GS-V_TH) of T₂ is double that of T₁, where V_GS and V_TH are the gate – to – source voltage and threshold voltage of the transistors, respectively. If the drain current and transconductance of T₁ are ID₁ and gm₁ respectively, the corresponding values of these two parameters for T₂ are
