Spice-Oriented Algorithm for Peak Search and Stability Assessment for Frequency Response

Abstract

In this study, we propose a Spice-oriented algorithm for peak search and stability assessment for the frequency response. We obtain the frequency response by using the sine-cosine circuit, Fourier transformation circuit and solution tracing-curve circuit, which have been developed in our previous studies. We combine the idea using a differentiator and a nonlinear limiter with them in order to search the exact peaks and propose a stability assessment algorithm based on the Floquet theory. In our algorithm, we can simulate almost all tasks with Spice.
