Answer Posted / ali umair khan
i will like to add a little bit to the above excellent posts
first the product of gain and bandwidth should be little
more than 1 at start up otherwise oscillations will not
occurs and as the feedback keeps going after some time it
must be reduced to the value of 1 , so that overdamped
oscillations must not occur, also their must be not any
phase inversion the phase difference b/w i/p and fb should
be 0 and 360 degree.
