Barkhausen's Criterion for sustained oscillations in an oscillator circuit states that:
1
The product of the loop gain and the feedback factor must be greater than one.
2
The loop gain must be zero.
3
The phase shift around the loop must be 180 degrees.
4
The product of the loop gain and the feedback factor must be one.
