1. Explain on the basic operation of the n-channel JFET. Draw the drain characteristics or output characteristics of the mentioned JFET type and denote the important parameters on the graph

2. Explain why the JFET is called a unipolar device. Your explanation must be based on the n-channel or p-channel device which is biased to operate as an amplifier

3. A JFET amplifier has a load resistance, RL= 500 kΩ. Find the ac drain resistance, rd if the amplification factor, μ and voltage gain, Av of the amplifier are 24 and 20 respectively

4. (i) What are the functions of MOSFET in electronic devices?
(ii)Why the N-channel MOSFET is considered better than the p-channel MOSFET
(ii) How does the MOSFET differ than the JFET?
(iii) Explain the basic operations of n-channel DMOSFET and EMOSFET
(iv) What does it mean “the channel is pinched off” in MOSFET

5. Design an operational amplifier with no change in output sign and voltage gain = 10 (Given Rin = 3 Ω and Vin = 5V)
