  2. 半导体三极管的SPICE模型 1.双极型晶体管的EM模型和GP模型 Ebers-Moll（即EM）模型和Gummel-Poon（即GP）模型是SPICE中的最常用的双极型晶体管模型。这两种模型均属于物理模型，其模型参数能较好地反映物理本质并且易于测量，便于理解和使用。

  3. 半导体三极管的SPICE模型 半导体三极管的EM模型

  4. 半导体三极管的SPICE模型 半导体三极管的GP模型 GP模型在EM模型上作了改进

  5. 半导体三极管的SPICE模型 半导体三极管部分模型参数在SPICE中的符号名称

  6. 半导体三极管的SPICE模型 半导体三极管2N2222的模型定义： MODEL Q2N2222  NPN(IS=1.87573e-15 BF=153.575NF=0.897646VAF=74  + IKF =0.410821ISE= 3.0484e- 09 NE=4BR=0.1 + NR=1.00903VAR=1.92063IKR=4.10821ISC=1.94183 e-12 + NC=3.92423RB=8.70248IRB=0.1RBM=0.1 + RE=0.111394RC=0.556972XTB=1.76761XTI=1 + EG=1.05CJE=1.67272 e-11VJE=0.83191MJE=0.23 + TF=3.573 e-10XTF=0.941617VTF=9.22508ITF=0.0107017 + CJC=9.98785 e-12VJC=0.760687MJC=0.345235XCJC=0.9 + FC=0.49264CJS=0VJS=0.75MJS=0.5 + TR=3.55487e-06PTF=0KF=0AF=1)

  7. SPICE仿真举例 例 用SPICE画出三极管2N2222的特性曲线 为了测试三极管的输出特性曲， 必须为三极管加上基极电源和集 电极电源，然后同时对基极电流 和集电极电压进行扫描。基极电 流每扫一步，集电极电压扫描一 周，输出集电极电流。下图对三 极管进行测试的电路，电路中 Um=0是为了输出电极电流。
