摘要：

Two approaches for analyzing single-loop feedback circuits are compared and contrasted in this paper. One approach is based on the return-ratio concept, and the other is based on two-port analysis. A frequent error in many popular texts-interchanging the computation of return ratio for a dependent source and loop gain of the idealized feedback network-is discussed. Assumptions commonly made in many texts when presenting two-port feedback analysis are examined for validity. Examples are given to highlight the differences between the two approaches.
