In Franklin Oscillator mainly, two COMMON EMITTER amplifier stages are employed
to provide 360 degree phase shift from
input to output.


The values of the different components
used in the franklin oscillator circuit are chosen to provide
an
overall loop gain of the two stages
|AB| slightly greater than unity.

The modulus value of AB represents the magnitude.


According to"BarkHausen" Criteria :-


To make an Amplifier as an Oscillator The magnitude of feedback factor AB should be greater than 1.
And
The Phase Shifting angle should be the multiple of 0,360...... Degrees
