| 摘 要： | 建立了PDP驱动芯片用高压LDMOS的SPICE子电路模型，该模型集成了LDMOS固有特性：准饱和特性、电压控漂移区电阻、自热效应、密勒电容等. 与其他物理模型和子电路模型比较，该模型不但能提供准确的模拟结果，而且建模简单快捷，另外该模型可较容易地嵌入SPICE模拟软件中. 模型的实际应用结果显示：模拟与实测结果误差在5%以内.

| Abstract: | A SPICE sub-circuit model is developed for high-voltage LDMOS transistors integrated in PDP driver ICs.The model accounts for intrinsic LDMOS phenomena such as the quasi-saturation effects,voltage-dependent drift resistance,self-heating effects,and Miller capacitance.In contrast to most physical or sub-circuit models,the proposed model not only provides precise simulated results,but also brings a very fast modeling procedure.Furthermore,the model also can be embedded in a commercial SPICE simulator easily.The simulation results using the presented models agree well with the measured ones and the error is less than 5%. |
