Abstract

In a recently published paper (Abuelma’atti, Analog Integr Circuits Signal Process 65:419–428, 2010) the start-up conditions for a class of sinusoidal RC oscillators are discussed. In this context, the validity of the well known Barkhausen condition for oscillation is challenged. In this comment some of the author’s conclusions are critically reviewed and the applicability of the Barkhausen criterion is demonstrated.
