A previous cut-insertion theorem for linear circuits and its application to a generalization of the elementary feedback theory are further extended. The new theorem is based on the splitting of an arbitrary node into two nodes and on the insertion between them and another arbitrary ldquoreferencerdquo node, of a three-terminal circuit which keeps the network currents and voltages unchanged. The system analysis is in turn performed on the equivalent cut network by means of the techniques for two… Expand

TLDR
The paper shows how to circumvent this difficulty: using the cut-inserted two-port which includes an independent current (voltage) source on one side of the cut and an independent voltage source on the other side one obtains the signal graph of the feedback system of order two. Expand

It is shown that introducing the second additional transformer in cascade connection with the first one and doing the cut in the wire between the transformers one may reduce this method to the previously known Cut-Insertion Theorem (CIT) method. Expand
Synthesis-oriented double-loop feedback model
TLDR
A single-loop synthesis-oriented feedback model is developed that enables the full synthesis of feedback amplifiers in a hierarchical and systematic way, and this model is subsequently extended to a double- loop synthesis model, so that also feedback amplifier with a characteristic input or output impedance—employing two feedback loops—can be synthesized through the same systematic approach.

TLDR
A novel general-purpose theorem for the analysis of linear circuits is stated and proven, and two equivalent parameters have to be found to determine the variable of interest, thus resulting in a more straightforward analysis technique. Expand
