The purpose of this research is to investigate various methods of inductor simulation to characterize and establish the performance constraints of each method. The majority of the methods are shown to produce a driving point impedance function having a single zero and a single pole. Therefore, a generalized equivalent circuit for most of the realizations studied is equivalent to an R-L-R circuit. A program called ROOTLO is developed as an aid in classical stability analysis. Degenerate circuit elements are presented as a conceptual aid in the design process. Several approaches to inductor simulation are investigated. These methods are the capacitively loaded VCT gyrator, the capacitively loaded CVT gyrator, other controlled sources, and the intrinsic parameter approach which does not require an external capacitor. Actual circuits including element values and operating characteristics are included for each realization considered. A brief description of the power inductor is included, and a class B VCT gyrator is given. Author
