First, we locate the ends of the load line. Substituting vD = 0 and the values given for VSS and R into Equation 10.5 yields iD = 2 mA. These values plot as point B in Figure 10.7. Substitution of iD = 0 and circuit values results in vD = 2 V. These values plot as point A in the figure. Constructing the load line results in an operating point of VDQ ≅ 0.7 V and IDQ ≅ 1.3 mA, as shown in the figure.
