Stability analysis of analog circuits that incorporate single-loop feedback is often associated with determining the loop transmission Axbeta and subjecting it to the Nyquist stability criterion. Various techniques have been developed to extract Axbeta from a circuit. However, proper application of the Nyquist stability criterion requires information about A and beta separately, before establishing their product. This paper will present a method to identify the feedback parameters A and beta of a circuit without breaking the loop unlike any other method seen previously. A second-order filter example will be provided to justify the proposed method.
