Barkhausen's criteria
Barkhausen's criterion is a necessary condition for oscillation but not a sufficient condition: some circuits satisfy the criterion but do not oscillate. [5] Similarly, the Nyquist stability criterion also indicates instability but is silent about oscillation. Apparently there is not a compact formulation of an oscillation … 더 보기 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). … 더 보기 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. 더 보기 • Nyquist stability criterion 더 보기 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 더 보기 Barkhausen's original "formula for self-excitation", intended for determining the oscillation frequencies of the feedback loop, involved an equality sign: βA = 1. At the time conditionally-stable nonlinear systems were poorly understood; it was widely believed that … 더 보기 웹"Barkhausen Criterion and Another Necessary Condition for Steady State Oscillations Existence", Proceedings 23th Conference Radioelektronika 2013, April 16-17, Pardubice, …
