Erratum: At 0:40, it is said that each RC-section should produce a phase shift of 120 degrees. This is physically impossible: A first-order RC-section can only produce phase shifts between 0 and -90 degrees. Instead, each RC-section should produce a phase shift of -60 degrees combined with the 180 degrees phase shift introduced by a negative amplification. This leads to three net shifts of 180 - 60 = 120 degrees, satisfying the Barkhausen criterion.
