QUESTION 3 [25 MARKS] Figure 4 shows the transfer curve of a network with an unknown channel Junction Field Effect Transistor (JFET). a) b) c) d) Time left 3:12:36 Identify the channel of the JFET and justify your answer. Draw and label the basic structure of the JFET construction in (a) above. Explain the conditions of the depletion region of the JFET in (a) when Vos = 0 V and Vos <0 V. Given that Vps is biased by a positive voltage. [10 Marks] [CO1, PO1, C21 Given the supply voltage of VD-15 V, design a voltage divider network using the JFET in (a) above. Take R₁= 1000Rs, R₂ = 150R, and V₁ =9 V. Please use the nearest standard resistor values that are provided in Appendix A. [15 Marks]
