Design a self-biased JFET circuit (Fig. 6) assuming VGS(0) = -1.3 and ipss=
20 mA. We require a VGS = -0.7. Assume a supply voltage of 15 volts. Draw the
load line for this circuit using Fig. 4b once you have selected the appropriate values
for the components. Does the load line intersect the VGS = -0.7 volt line at the
computed in point?
