Question 1

The parameter of n-channel depletion mode MOSFET are Vth = -2.5V and Kn =1 mA/V2 and VGS= 0V, VDS = 0.8 V then what will be the value of current ID ?

Question 2

Find the operating region of the MOSFET :

Question 3

The PMOS transistor in fig. has parameters ,and

If then the value of are

Question 4

The given circuit R1 = 20 KΩ, RD = 10 KΩ, and R2 = 30 KΩ, VDD = 5 V, VT of the MOSFET is 1 V. Take the value of = mA/V2. Then power dissipated by the MOSFET is _______ mW.

Question 5

The NMOS and PMOS transistor are matched with = 1V, Assume λ = 0 for both devices.
