Abstract

The comment is related to the recently published papers given in [Singh, V. (2006). Analog Integrated Circuits and Signal Processing, 48, 251---255; Singh, V. (2007). Analog Integrated Circuits and Signal Processing, 50, 127---132.] which depict the failure of Barkhausen oscillation building up criterion. Many counterexamples have been given in order to substantiate such viewpoint. We would like to review these reported circuit examples and present the treatment of Barkhausen oscillation criterion.
