A Comprehensive Nodal/Branch Circuit Analysis Including Fixator-Norator Pairs in Analog Circuits

A generalized approach is proposed to solve for analog circuits, analysis and design. By directly introducing fixator-norator pairs (FNP) into the branch conductance matric of a linear analog circuit we integrate analysis and design into one process. This approach is different from the traditional Modifies Nodal Analysis (MNA) in two aspects. First, it includes FNPs as well as independent voltage sources into the nodal/branch solution. In fact, FNPs bring the design constraints right into the analysis making the two combined, and one single process. The second difference is that, here we choose a tree-branch approach rather than nodal one. This results in computational efficiency.
