Find the Q-point for the p-channel JFET circuit in Figure.

2. 3. 5. Using the data when the gate voltage is 0, explain how you could use your JFET as a two-terminal current source that gives a current of Ipss. (a) Does the experimental data indicate that the transconductance is a constant at all points? (b) From your experimental data, what evidence indicates that a JFET is a nonlinear device? Why should a JFET be operated with only reverse bias on the gate source?

3. In a certain n-channel JFET, Ipss= 8 mA and Vp=-4 V. (a) Determine the value of Ves for maximum drain current. (b) Calculate the drain current for VGs=-5 V (c) Calculate the drain current for Ves=-2 V (d) Determine the maximum value of VGs for cut-off condition.

Please solve it.
