So, from oscillator theory I know that we need to have 360 phase shift from output to input. But, if we have 3 inverters, each of them make 180 deg phase shift, that is not 360 but it still oscillate.
I understand working principle of ring oscillator... I'm just confused about this theoretical part about the phase.
