Question

Figure 1 shows the transfer curve of a network with an unknown channel Junction Field Effect Transistor (JFET).

(i) Identify the channel of the JFET; justify your answer.

(ii) Given the supply voltage of 16 ?, design a voltage divider network using the JFET in (i) above. Take R1 = 1400RS; R2 = 180RS; and VD = 10 V. Please use the nearest standard resistor values.

(iii) With the obtained standard resistance values in (ii) above, determine the new IDQ and VGSQ, using the mathematical approach only.
