Abstract
Over the years researchers have developed and reported a large number of sinusoidal oscillator circuits and classified them as enjoying fully uncoupled independent control of frequency and condition of oscillation. This classification is based on obtaining the frequency and the condition of oscillation using the Barkhausen criterion. This paper serves as a caution as it appears that this classification is incorrect. Experimental results obtained from recently published circuits; that support this caution, are included.
