摘要
针对传统SGP模型的不足,介绍了一种新型的BJT模型MEXTRAM504及其等效电路,与传统模型相比,MEX-TRAM显示了极高的准确度。由于特别增加了描述基区缓变和基区载流子复合的两个参数,使MAXTRAM适合模拟加入SiGe工艺技术的HBT,模拟曲线与Medici的模拟相当吻合,为射频器件设计和电路模拟奠定了良好的基础。
Due to the deficiency of conventional models, a new BJT model MEXTRAM, level 504 and its equivalent circuit are introduced. Compared with former models,it exhibits perfect accuracy. MEXTRAM specially uses two parameters for SiGe HBT model, and experiments show that the simulation curves have a very good agreement with Medici simulation data. It is the meaning for the advanced device design and circuit simulation.
