Presidential Young Investigator Award: Simulation of Switching Filter and Phase-Lock Loop Circuits

白色 本研究主要针对高频电路与元件的建模、分析与模拟三个主题：1。 多极加速三维互连分析; 2. 时钟模拟电路的仿真; 3. 微机电（MEM）器件的仿真。 对于互连分析，多极加速电路分析方法被应用于确定有效和准确的方法来模拟串扰效应和执行电感提取的问题。 在时钟模拟电路的仿真中，正在开发用于详细仿真开关电容滤波器和开关功率转换器的算法。 MEM器件模拟的初始工作探索模拟机械力、静电力和流体力之间的相互作用，同时考虑外部电路引起的行为。 用于分析静态和瞬态行为的算法正在研究中。

White This research is on three topics in modeling, analysis, and simulation of high-frequency circuits and devices: 1. Multipole accelerated 3-D interconnect analysis; 2. Simulation of clocked analog circuits; and 3. Simulation for micro-electro-mechanical (MEM) devices. For the interconnect analysis, multipole-accelerated approach to circuit analysis is being applied to problems of determining effective and accurate methods to simulate cross-talk effects, and perform inductance extraction. In simulation of clocked analog circuits, algorithms for detailed simulation of switched-capacitor filters and switching power converters are being developed. Initial work in MEM device simulation explores simulating interactions between mechanical, electrostatic and fluidic forces, while simultaneously accounting for the behavior induced by the external circuitry. Algorithms for analyzing both static and transient behavior are being investigated.
