Fast simulation of weakly nonlinear circuits based on multidimensionalinverse Laplace transform

Wang, Tingting, 王婷婷 January 2012 (has links)
This dissertation presents several solutions on the simulation of weakly nonlinear circuits. The work is motivated by the increasing demand on fast yet accurate simulation methods circuits (IC)s, and the current lack of such methods in the electronic design automation (EDA) / computer-aided design (CAD) community. Three types of frequency domain methods are studied to analyze weakly nonlinear circuits. The first method employs numerical multi-dimensional inverse Laplace transform based on Laguerre function expansion. An adaptive mesh refinement (AMR) technique is developed and its parallel implementation is introduced to speed up the computation. The second method applies a Fourier series based algorithm to invert Laplace transform. The algorithm is straightforward to implement, and gives increasing accuracy with increasing number of frequency sampling points. It employs a fast Fourier transform (FFT)-based method to directly invert the frequency domain solution. Its parallel routine is also studied. The third method is based on Gaver functional. It enjoys a high accuracy independent of the number of sampling points, and for multidimensional simulation, only the diagonal points in the matrix are required to be computer, which can be further speeded up by parallel implementation. Numerical results show that the aforementioned three methods enjoy good accuracy as well as high efficiency. A comparative study is carried out to investigate the strengths and drawbacks of each method. / published_or_final_version / Electrical and Electronic Engineering / Master / Master of Philosophy

Representation of multivariable-controlled MOSFET nonlinearities in transient analysis programs

Ma, Hong January 1991 (has links)
This thesis deals with the modelling and circuit simulation problems of nonlinear electronic devices. Emphasis has been aimed at MOSFET devices. A Piecewise Linear (PWL) modelling scheme has been proposed for a general four-terminal nonlinear charge device. The charge functions are all nonlinear and are approximated by PWL functions. If analytical expressions for the nonlinear functions are not available, PWL function approximations can be built from a data table in which discrete data points are recorded. In the time domain, the critical-damping-adjustment (CDA ) scheme is used as the integration rule in the discretization of dynamic charge devices. Piecewise linear modelling combined with the CDA integration scheme gives a fast yet adequately accurate simulation algorithm. The algorithm is based on linear analysis because the entire circuit becomes linear with PWL modelling of nonlinear elements. In order to avoid an iterative solution, PWL region extrapolation is permitted when the circuit solution switches PWL regions. The extrapolation approximation will generate an overshoot error in the solution vector. However, with caution in the selection of the integration step size, the error can be limited to an acceptable range. Two types of MOSFETs have been modelled and simulated with the algorithm introduced in this thesis, and satisfactory results have been obtained as compared to Newton's iteration solutions. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
