Barkhausen criterion

While designing an electronic oscillator the Barkhausen criterion plays a very important role. It states that there should be two important criteria that must be met to produce oscillations: The oscillator circuit must contain an amplifier with gain > 1 and the circuit must have a positive feedback to create and sustain oscillations…
