1. Explain on the basic operation of the n-channel JFET. Drawthe drain characteristics or output characteristics of thementioned JFET type and denote the important parameters on thegraph
2. Explain why the JFET is called a unipolar device. Yourexplanation must be based on the n-channel or p-channel devicewhich is biased to operate as an amplifier
3. A JFET amplifier has a load resistance, RL= 500 kΩ. Find the acdrain resistance, rd if the amplification factor, μ and voltagegain, Av of the amplifier are 24 and 20 respectively
4. (i) What are the functions of MOSFET in electronicdevices?
(ii)Why the N-channel MOSFET is considered better than thep-channel MOSFET
(ii) How does the MOSFET differ than the JFET?
(iii) Explain the basic operations of n-channel DMOSFET andEMOSFET
(iv) What does it mean “the channel is pinched off†in MOSFET
5. Design an operational amplifier with no change in output signand voltage gain = 10 (Given Rin = 3 Ω and Vin = 5V)
