State barkhausen criteria

WebA small change In DC power supply or noise component in oscillator circuit can start oscillation and to maintain oscillation in circuit must satisfy Barkhausen’s criterion. Fig1 block diagram of oscillator V I N =input voltage V o =output voltage A= forward path gain β = small fraction of O/p signal is fed back to I/p WebThat means: The loop gain magnitude at the frequency fo will be > 0 dB and the Barkhausen condition is (over-)fulfilled. The circuit oscillates at a frequency fo (where the phase condition is fulfilled). Note that for all frequencies below fo the loop gain is even larger than at f=fo. Nevertheless, the frequency for steady-state oscillations is ...
