WebThe Barkhausen criteria are usually applied to analyze sine wave type oscillator circuits (Wien bridge, etc.) where a small signal, such as thermal noise, is exponentially amplified around the positive feedback loop to create the output signal. WebBarkhausen criteria. The Barkhausen criteria states that the circuit must have a loop gain of unity or greater, and have a phase shift that is a multiple of 360°. ... Steady State Amplitude (SSA).
