The research proposed here centers around the simulation and computer aided design (CAD) of nonlinear analog circuits and systems with large signal excitation, and of circuits with mixed analog and digital signals (e.g. analog-to-digital converters). While there are many excellent schemes for simulation and CAD of digital circuits, there are no satisfactory methods for the analysis of large-signal analog circuits. Currently there is a trend towards monolithicly integrating analog circuits to obtain the same performance, cost and reliability improvements obtained with digital circuits. This can only be achieved if new and accurate computer aided design techniques are developed. The research to be supported by this award will develop and experimentally verify novel nonlinear frequency-domain and nonlinear z-domain simulation techniques and apply them to a CAD environment.

这里提出的研究集中于具有大信号激励的非线性模拟电路和系统以及具有混合模拟和数字信号的电路（例如模数转换器）的仿真和计算机辅助设计（CAD）。 虽然数字电路的仿真和CAD有很多优秀的方案，但对于大信号模拟电路的分析还没有令人满意的方法。 目前有一种趋势是单片集成模拟电路，以获得与数字电路相同的性能、成本和可靠性改进。 只有开发出新的、准确的计算机辅助设计技术才能实现这一点。 该奖项支持的研究将开发并实验验证新型非线性频域和非线性 z 域仿真技术，并将其应用于 CAD 环境。
