  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
