摘要
基于标准的Mextram双极器件紧凑模型,根据双极NPN晶体管的结构,分析器件模型参数与发射极长度和宽度等几何尺寸的关系,引入多个尺寸相关的系数,对相关的模型参数进行了修正,建立了一种可缩放的双极器件模型。经过多套双极工艺的实际验证,结果表明提出的修正模型具有良好的尺寸缩放功能,对不同尺寸的双极晶体管的拟和误差都比使用比例因子的方法大幅减小,对双极电路设计仿真具有很好的应用价值。
In this paper,a geometrically scalable compact model for bipolar junction transistors,derived from the standard Mextram model,is proposed.According to the physical structure and critical dimensions of an NPN transistor,such as the length and width of its emitter,the initial model parameters are modified by introducing several dimension-related factors.The revised model is verified across various process technology nodes and platforms.The results demonstrate that our model has a remarkable scaling capability,and the RMS values are significantly lower than those of a MULT-scaling model.Therefore,our scalable compact model has a promising application in SPECTRE simulation of bipolar transistors in integrated circuits.
