The objective of assignment is to design and simulate Wien Bridge oscillator using IC op-amp and calculate of its frequency oscillation.
Specification: Different specification of design for each student. Please refer Table 1.
1. Power supply = ± 12V.
2. Power consumption, < 10mW.
3. Oscillation frequency is targeted between 100 KHz to 200 KHz.
Deliverables:
1. You are expected to design a Wien Bridge oscillator by connecting the variable resistor, Rf = 10 kΩ) resistive to the inverting inputs. Adjust Rf to observe the waveform output.
2. Observe the waveform at both inputs and output point and measure the peak to peak voltage.
3. Compute the expected frequency of oscillation from the equation. Compare the calculation and simulation results.
4. Show the design steps in details and calculate the components value.
5. Simulate the designed circuit using LTPSICE to verify its operation.
6. Discuss how to make a Wien Bridge tune to different frequencies.
7. You are expected to present your results in the form of a Technical Report.
