In electronicsthe Barkhausen stability criterion is a mathematical condition to determine when a linear electronic circuit will oscillate.
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 criterion is that a complex pole pair must be placed on the imaginary axis of the complex frequency plane if steady state oscillations should take place.
Barkhausen Stability Criterion
In the real world, it is impossible to balance on the imaginary axis, so in practice a steady-state oscillator is a non-linear circuit:. Barkhausen’s criterion is a necessary condition for oscillation but not a sufficient condition: Apparently there is not a compact formulation of an oscillation criterion that is both necessary and sufficient.
Barkhausen’s original “formula for self-excitation”, intended for determining the oscillation frequencies of the feedback loop, involved an equality sign: From Wikipedia, the free encyclopedia. For the noise in the output of a ferromagnet upon a change in the magnetizing force, see Barkhausen effect.
