Understanding the Clapp Oscillator
The Clapp oscillator is a type of LC oscillator that utilizes a combination of inductors and capacitors to generate oscillations. The role of capacitors in this oscillator is crucial for determining the frequency and stability of the output.
Capacitor Roles in Voltage Divider
- C1 (Upper Capacitor): This capacitor is part of the voltage divider. Its primary role is to set the upper limit for the voltage across the tank circuit.
- C2 (Lower Capacitor): C2 completes the voltage divider setup. It influences the feedback received by the amplifier to sustain oscillation.
- C3 (Third Capacitor): C3 is connected in parallel with the inductor and is critical for determining the frequency of oscillation.
Importance of C3's Value
- Stability of Oscillation: C3 must have a minimum value to ensure that the oscillation frequency remains stable and predictable. A lower value of C3 allows for a higher resonance frequency, which is essential for proper operation.
- Feedback Factor: The feedback loop in the oscillator requires an optimal capacitance to maintain consistent oscillation. The minimum value of C3 is crucial for this feedback mechanism.
Conclusion
In summary, for the perfect operation of a Clapp oscillator, the third capacitor (C3) must have the minimum value. This allows for better frequency stability and effective feedback, ensuring that the oscillator functions correctly. Hence, the correct answer is option 'C'.
