Abstract
The present article is related to the recently published paper given in Singh (Analog Integr Circuits Signal Process, 62, 327–332, 2010), which depicts the failure of Barkhausen criterion concerning the determination of condition of oscillation for startup of sinusoidal oscillation. In particular, the sinusoidal oscillator circuit considered in this article is one of the possible four alternatives of the Wien-bridge oscillator (WBO). In other previous articles by the same forementioned author ...
