What is LC oscillator explain?
LC oscillator is a kind of oscillator where a tank circuit (LC) is used to give the required positive feedback for maintaining the oscillations. lc-oscillator-and-its-symbol. This circuit is also called as LC tuned or LC resonant circuit. These oscillators can understand with the help of FET, BJT, Op-Amp, MOSFET, etc.
What are the types of LC oscillators?
Difference between LC and RC Oscillator
| RC Oscillator | LC Oscillator |
|---|---|
| These oscillators are applicable at medium and low frequencies | These oscillators are applicable at high frequencies |
| The best examples of RC oscillator are wein bridge and phase shift | The best examples of LC oscillators are Colpitts, clap, hartley, etc. |
What is the application of LC oscillator?
The LC circuit is used to select or generate a specific frequency signal. The application of LC circuits is reflected in many electronic devices, especially radio devices, such as transmitters, radio receivers and television receivers, amplifiers, oscillators, filters, tuners and frequency mixers.
What is the frequency range of LC oscillator?
1 MHz to 500 MHz
These are also known as LC oscillators, resonant circuit oscillators or tank circuit oscillators. The tuned circuit oscillators are used to produce an output with frequencies ranging from 1 MHz to 500 MHz Hence these are also known as R.F.
What are the draw back of LC oscillator?
One of the main disadvantages of the basic LC Oscillator circuit we looked at in the previous tutorial is that they have no means of controlling the amplitude of the oscillations and also, it is difficult to tune the oscillator to the required frequency.
What is the importance of LC circuit?
LC circuits are also used for producing signals at a particular frequency or accepting a signal from a more complex signal at a particular frequency. The main purpose of an LC circuit is usually to oscillate with minimum damping, so the resistance is made as low as possible.
What are the limitations of LC oscillator?
Disadvantages of LC oscillators The operating frequency of the oscillator is not constant. It is due to the various components involved in the circuit. The operating frequency can shift if any component in the feedback circuit is changed. It is not suitable at low frequencies.
What are the drawbacks of LC oscillator?
Drawbacks of LC circuits
- Frequency instability.
- Waveform is poor.
- Cannot be used for low frequencies.
- Inductors are bulky and expensive.
What are the limitations of LC oscillators?
Why are LC circuits called tanks?
An older name is “tank circuit,” because its operation is analogous to a tank in a fluid system, in which the dimensions of the tank define the natural frequency observed when fluid is pulsed through the tank. Learn More: LC Oscillator Has 1% THD.
What is the advantage of LC oscillator?
Frequency of Oscillations in Hartley Oscillator
What is a frequency range of LC oscillator?
Often, its operating oscillation frequency ranges from 20KHz to 20MHz, and you can realize it using Op-Amps, FET, and BJT. The Colpitts oscillator is a type of LC oscillator invented by Scientist Edwin Colpitts in 1918. Its tank circuit comprises an inductor and two capacitors.
Can a LC oscillator be used to generate visible light?
Therefore unless one generalizes the notions of “inductor” and “capacitor” (and the other circuit elements) far outside the ordinary, the answer is no, an LC oscillator cannot produce visible light. Ref. Can an LC oscillator be used to generate visible light?
What are the essential components of a feedback LC oscillator?
Essentials of LC oscillator. Fig shows the block diagram of an oscillator. Its essential components are (i) tank circuit, (ii) amplifier and (iii) feedback circuit. (i) Tank circuit : It consists of inductance coil (L) connected in parallel with capacitor (C). The.
