Abstract

To improve analog design automation (ADA) of electronic circuits, an interactive system for symbolic analysis called SIASCA is introduced. SIASCA includes schematic capture of a more general class of analog circuits, namely: operational transconductance amplifiers and current conveyors. The options of analysis are focused on calculating simplified symbolic expressions (SEs), representing the dominant behavior of a circuit, for AC and noise analysis. To minimize complexity in manipulating SEs, all active devices are modeled at different levels of abstraction by using nullors. Several examples demonstrate the suitability and usefulness of SIASCA to be used within ADA environments.
