METHOD AND APPARATUS FOR ANALYSING AND MODELING OF ANALOG SYSTEMS |
摘要 |
Method and apparatus for analysis and modeling of analog systems. A system is partitioned for analysis by linearizing each non-linear element so that a large-signal operating point or some other weighted behavior of the non-linear element is captured in a linearized model. The linearized models are collapsed with linear elements so that the analog system is represented as a constant linear system with at least one, but possibly more independent energy sources. Once the system is partitioned in this way, an efficient steady-state non-linear analysis is performed to produce output responses at points of interest. Optionally, the steady-state analysis can be used to generate a macromodel of the analog system that can be used for system level analysis. A computer program product can be used to implement the invention, which can be applied to various types of analog systems, including analog circuits. |
