摘 要:
基于规范化分段线性模型技术,建立了高压DMOS器件的SPICE宏模型用于功率集成电路的仿真.从等效电路模型出发,利用Powell算法找到规范化分段线性模型的最佳系数,从而利用节点电压可以直接描述DMOS器件的各种非线性特性.该模型不仅准确性高,而且仿真速度快、收敛性好.最后,给出了仿真与测试的对比结果,证明了模型的有效性和准确性.[著者文摘]

Abstract:
A novel macro-model of high-voltage DMOS for power ICs is proposed according to the canonical piecewiselinear model technique. The method describes nonlinear characteristics directly as functions of node voltage. We employ the Powell algorithm, which gives higher accuracy without the convergence problem and with lower analysis time. Finally, a Comparison of simulation results and measurement results in application to power ICs is reported.[著者文摘]
