Abstract

The paper presents an improvement of sensitivity and tolerance analysis method for the Voltage-Controlled Oscillator (VCO) circuits with Van der Pol model. The tolerance analysis method is based on the Monte Carlo Analysis (MCA) and on the Fast Monte Carlo Analysis (FMCA) based on the circuit transfer function. The circuit sensitivities are computed by means of the derivatives of the circuit transfer functions. A practical and reliable approach has been developed and implemented in a computation program for linear (nonlinear piecewise-linearized) analog circuits. The circuits can contain any type of passive elements, independent and controlled sources. Powerful modified nodal approaches to build the mathematical model combined with some symbolic computation strategies have been exploited, in order to reduce the computational effort and to minimize the numerical errors. A software tool was conceived as a useful and valuable support for research and design engineers.

用Van der Pol模型模拟振荡器电路的灵敏度和容差分析

本文提出了一种改进的范德波模型压控振荡器(VCO)电路的灵敏度和容差分析方法。公差分析方法是基于蒙特卡罗分析(MCA)和基于电路传递函数的快速蒙特卡罗分析(FMCA)。利用电路传递函数的导数计算电路灵敏度。本文提出了一种实用可靠的方法，并在线性(非线性分段线性化)模拟电路的计算程序中实现。电路可以包含任何类型的无源元件，独立和受控源。为了减少计算量和减小数值误差，采用了强大的修正节点方法与一些符号计算策略相结合来建立数学模型。软件工具被认为是对研究和设计工程师有用和有价值的支持。
