Abstract

The possibility of obtaining the frequency-domain dynamic model of a circuit from transient analysis data provided by a circuit simulator is shown. The computer-aided design (CAD) program FREDOMSIM, which governs the simulations, processes the output data, and supplies the results in a well suited manner for design optimization, is introduced. Feedback circuits are modeled with all their feedback loops open, so that the designer can optimize systems by proper a posteriori loop closures. The characterization with the loops closed is also given
