Symbolic Analysis of Large Analog Circuits

本研究探索复频域大型线性或线性化集成电路符号分析的算法和技术。该方法是以符号形式提取电路的传递函数。在大型电路的情况下，以扩展或嵌套格式生成近似的符号网络函数。基于微扰和树枚举两种方法都被使用。符号算法和仿真器被集成到模拟设计自动化系统中。

This research explores algorithms and techniques for symbolic analysis of large linear or linearized integrated circuits in the complex frequency domain. The approach is to extract transfer functions of circuits in symbolic form. In the case of large circuits, approximate symbolic network functions, in expanded or nested format, are generated. Both perturbation-based, and tree enumeration approaches are being used. The symbolic algorithms and simulators are being integrated into an analog design automation system.
