2. ENGR43 P12.24 Use LOAD-LINE Analysis to Find vo(t) for the Ckt below
Note: This a pFET Circuit

3. The pFET Characteristic

4. P12.24 GamePlan
Draw LoadLine for the 1 kΩ Resistor load, then find the operating (vDS, iD) Values corresponding to This Set of vGS values
vGS = [7v + 1V•sin(0)] −10V
This is VGSQ = −3 V
vGS = [7v + 1V•sin(π)] −10V
This is vGS,max = −4 V
vGS = [7v + 1V•sin(3π/2)] −10V
This is vGS,min = −2 V
