A new symbolic program package for the interactive design of analog circuits

Abstract

A new program package which constitutes an environment for the interactive exploration and improvement of analog circuit topologies is presented in this paper. The environment is provided with functionalities which permit the graphical schematic entry of the circuit, the symbolic analysis, the approximation of the symbolic results, the use of an external numerical simulator and the graphical postprocessing of both the symbolic and numerical simulation results. These functionalities allow us to immediately evaluate the influence of both topology and component value changes on the circuit behavior. The result is useful for educational/training purposes and for the interactive synthesis of new high-performance analog circuits.
