Question:

a. Determine VDS for VGS = 0 V and ID = 6 mA using the characteristics of Fig. 6.11.
b. Using the results of part (a), calculate the resistance of the JFET for the region ID = 0 to 6 mA for VGS = 0 V.
c. Determine VDS for VGS = - 1 V and ID = 3 mA.
d. Using the results of part (c), calculate the resistance of the JFET for the region ID = 0 to 3 mA for VGS = -1 V.
e. Determine VDS for VGS = -2 V and ID = 1.5 mA.
f. Using the results of part (e), calculate the resistance of the JFET for the region ID = 0 to 1.5 mA for VGS = -2V.
g. Defining the result of part (b) as r0, determine the resistance for VGS = - 1V using Eq. (6.1) and compare with the results of part (d).
h. Repeat part (g) for VGS = -2 V using the same equation, and compare the results with part (f).
i. Based on the results of parts (g) and (h), does Eq. (6.1) appear to be a valid approximation?
