摘要

在分析多晶体管电路时，需要对电路的时间延迟或功耗进行评估。由于晶体管模型的复杂性，产生了一些复杂的方程，从中不能得到紧凑形式的解，也不能得出适当的物理见解。在这方面，本文提出了两项贡献。第一种是应用于MOS晶体管的全解析参数提取方法。二是采用时延或功耗等效准则，用合适的等效电阻对MOS晶体管进行建模，简化MOS电路分析的定量方法。根据第二个贡献，在导出表达式中使用提取的参数对参数提取方法进行了验证。与其它模型相比，所提出的模型与仿真结果吻合较好。

Parameter extraction and modelling of the MOS transistor by an equivalent resistance

ABSTRACT During the analysis of multi-transistor circuits, the need arises to evaluate the time delay or the power consumption of the circuit. Due to the complexity of the transistor model, several complicated equations arise from which a compact-form solution cannot be obtained and a suitable physical insight cannot be drawn. With this regard, two contributions are presented in this paper. The first one is a fully analytical parameter extraction approach to be applied on the MOS transistors. The second one is a quantitative method for simplifying the analysis of MOS circuits by modelling the MOS transistor by a suitable equivalent resistance adopting the time-delay or the power-consumption equivalence criteria. The parameter-extraction method is verified by using the extracted parameters in the derived expressions according to the second contribution. Compared to other representations, the agreement of the proposed model with the simulation results is very good.

期刊介绍： Mathematical and Computer Modelling of Dynamical Systems (MCMDS) publishes high quality international research that presents new ideas and approaches in the derivation, simplification, and validation of models and sub-models of relevance to complex (real-world) dynamical systems. The journal brings together engineers and scientists working in different areas of application and/or theory where researchers can learn about recent developments across engineering, environmental systems, and biotechnology amongst other fields. As MCMDS covers a wide range of application areas, papers aim to be accessible to readers who are not necessarily experts in the specific area of application. MCMDS welcomes original articles on a range of topics including: -methods of modelling and simulation- automation of modelling- qualitative and modular modelling- data-based and learning-based modelling- uncertainties and the effects of modelling errors on system performance- application of modelling to complex real-world systems.
