ECE65 (Spring 2006), Midterm Solution Notes: 1. Write your answers on these three sheets. 2. For each problem, 20% of points are alloacted for the correct final answer. 3. Use the following information in solving or designing circuits: OpAmps are poweredby±15 V power supplies (power supplies not shown), have a unity-gain bandwidth of106Hz, a short-circuit current limit (maximum output current limit) of 250 mA, and aslew rate of 1 V/μs. Diodes are made of Si. 4. In circuit design, use commercial resistorand 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 an integer). You can also use 100μHinductors.Problem 1.Am radio stations are assigned a bandwidth of 20 kHz. Design a band-passfilter for the tuner of an AM radio station tuned to 980 kHz (center frequency).
