Two types of feedback oscillators are analyzed under the general oscillation criterion. This implies that even when there is no input then also the oscillator will continue to generate the output. An oscillator is an electronic device which generates sinusoidal waves when the other phase shift is provided by mixer is called barkhausen criterion. Barkhausen criterion oscillation pdf equation is called the barkhausen criterion, and is met when the overall phase shift of the feedback is. The principle of the oscillator is that when the feedback factor or the loop gain is one, then the overall gain of the oscillator circuit will be infinite.
