Question

Advantages and disadvantages of colpitts oscillator

Answer 1

There are various advantages and disadvantages of "Colpitts Oscillator" 
Advantages:
The one big advantage of this oscillator is that it's performance remains very good even the high frequency.
This type of oscillator have the capacity to produce more purer waves.
This oscillator generally also have the wide range of operation capacity .

Disadvantage:
The one main disadvantage is it's hard to construct .
Whenever the capacitor value change it becomes more difficult to adjust feedback.
Because of the circuit bulkiness the cost increases also.

Answer 2

The Colpitts Oscillator is designed to produce sinusoidal oscillations using two centre-tapped capacitors placed in series with a parallel inductor to create its resonance tank circuit.

Advantages:

The Colpitts Oscillator can be used in high frequency to produce pure sinusoidal waveform because of low impedance paths of the capacitors at high frequencies.

It has wide operation range from 1 to 60 MHz.

Disadvantages:

It is difficult to design.

It has poor isolation property.

Because the circuit is complicated, the cost to construct is high.
