PHASE OSCILLATOR OBJECTIVE: To study the operation and characteristics of oscillators based on op-amps. Part 1 Design the following op-amp circuit (Fig 1)b to have a gain of about 60: Values for circuit on left: R1=R2=10K 60 * R2 = 600K V+ = 10 volts V- = -10 volts

Apply a signal to input and observe to the input and observe the signal at point D, as a function of frequency. D AS FUNCTION OF FREQUENCY The formula for the frequency of the given op-amp circuit is: Theoretical Frequency = 1 / (2 Π *√6*RC)=1.032Khz Experimental Frequency=1.05 The gain for the circuit is 3.66 Design the three stage RC filter network on the right side of Fig 1 with a gain of 1/29 and a phase shift of 180 at 1KHz. C =0.063μF R = 1kΩ Note R2 should be greater than R. Why? To reduce the load factor. To ensure that the output of the RC network does not load R2 at the inverting input of the op-amp The signal at point D is a sine wave with an amplitude of 200 mV at 1KHz.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
