In electronics, the Barkhausen stability criterion is a mathematical condition to determine when a linear electronic circuit will oscillate. It was put forth in 1921 by German physicist Heinrich Georg Barkhausen (1881–1956). It is widely used in the design of electronic oscillators, and also in the design of general … See more Barkhausen's criterion applies to linear circuits with a feedback loop. It cannot be applied directly to active elements with negative resistance like tunnel diode oscillators. The kernel of the … See more It states that if A is the gain of the amplifying element in the circuit and β(jω) is the transfer function of the feedback path, so βA is the See more • Nyquist stability criterion See more Barkhausen's original "formula for self-excitation", intended for determining the oscillation frequencies of the feedback loop, involved an … See more WebThat means: Yes, the Barkhausen condition may be applied to steady-state oscillations only. With other words - if the amplitude condition is met ( T(jωo) =1 or even >1) and the phase condition is NOT met, we can have decaying or even rising oscillations immediately after power switch-on.
