Solution of ECE65 Final (Winter 2007) Notes: 1. For each problem, 20% of points is for the “correct” final answer. 2. Messy, incoherent papers lose point! Explain what you are doing!3.OpAmps have a unity-gain bandwidth of 106Hz, a maximum output current limit of100 mA, and a slew rate of 1 V/μs. OpAmps are powered by±15 V power supplies,4) Use the following information in designingcircuits: BJT Si transistors haveβ= 400,βmin= 200,rπ= 3 kΩ, andro= 100 kΩ.Use 5% tolarence commercial resistor and capacitor values of 1, 1.1, 1.2, 1.3, 1.5, 1.6, 1.8,2, 2.2, 2.4, 2.7, 3., 3.3, 3.6, 3.9, 4.3, 4.7, 5.1, 5.6, 6.2, 6.8, 7.5, 8.2, 9.1 (×10nwherenis aninteger). You can also use 5 mH inductors.Problem 1.Find the Thevenin Resistance of the following circuit (Assume OpAmp isideal). (10 pts) Solution of ECE65 Final (Winter 2007) 1
