Steady-state analysis techniques for coupled device and circuit simulation

Hu, Yutao 28 May 2004 (has links)
The focus of this work is on the steady-state analysis of RE circuits using a coupled device and circuit simulator. Efficient coupling algorithms for both the time-domain shooting method and the frequency-domain harmonic balance method have been developed. A modified Newton shooting method considerably improves the efficiency and reliability of the time-domain analysis. Three different implementation approaches of the harmonic balance method for coupled device and circuit simulation are investigated and implemented. These include the quasi-static, non-quasi-static, and modified-Volterra-series approaches. Comparisons of simulation and performance results identify the strengths and weakness of these approaches in terms of accuracy and efficiency. / Graduation date: 2005

Analysis and modeling of single-ended and differential spiral inductors in silicon-based RFICs

Watson, Adam C. 02 December 2003 (has links)
A new comprehensive wide-band compact modeling methodology for single-ended spiral inductors and differential spiral inductors is presented. The new modeling methodology creates an equivalent circuit model consisting of frequency-independent circuit elements for use in circuit simulators. A fast automated extraction procedure is developed for determining the circuit element values from two-port S-parameter measurement data. The methodology is extremely flexible in allowing for accurate modeling of general classes of inductors on high or low resistivity substrate and for large spirals exhibiting distributed trends. The new modeling methodology is applied to general classes of spirals with various sizes and substrate parameters. The presented compact modeling methodology has major benefits including greatly reducing model extraction time in comparison with currently available models based on optimization methods. To demonstrate the accuracy in comparison with past models a number of measurement data sets are used for sample extractions. A developed computer program is presented and used for circuit model extractions. Results are presented when the computer program is applied to a high-volume inductor extraction. The extracted models show excellent agreement with the measured data sets over the frequency range of 0.1 to 10 GHz. / Graduation date: 2004
