Common Emitter Amplifier:
The Hartley oscillator is a type of LC oscillator used for generating sinusoidal waves. It consists of two transistors, an inductor, and two capacitors. In a Hartley oscillator, a common emitter amplifier configuration is used.
Explanation:
- In a common emitter amplifier configuration, the input signal is applied to the base of the transistor, and the output is taken from the collector.
- The common emitter configuration provides high voltage gain and moderate input impedance, making it suitable for oscillator circuits like the Hartley oscillator.
- The feedback from the collector to the base through the inductor and capacitors in the Hartley oscillator creates the necessary conditions for oscillation.
Advantages of using a common emitter amplifier for the Hartley oscillator:
- Provides high voltage gain
- Allows for frequency stability
- Offers good harmonic suppression
- Ensures proper amplitude and frequency of the output waveform
In conclusion, the common emitter amplifier configuration is the most suitable choice for the Hartley oscillator due to its ability to provide the necessary characteristics for oscillation and signal generation.
