摘要
分析了VDMOSFET导通电阻模型 ,提出了单胞尺寸是影响导通电阻的最重要因素。单胞尺寸的最佳化选择可使器件的特征导通电阻RonA(单位面积导通电阻 )最小 ,并通过大量理论计算给出击穿电压为5 0V时的最佳单胞尺寸。
The important factor of the effects of on-state resistance of cell dimention is presented through the analysis of the model for VDMOSFET'S on-state resistance. Through the optimal election of cell dimension,the smallest special on-state resistance R onA (the on-state resistance of unit area) is obtained.In the meantime,the optimal cell dimention of BV DS =50 V is also given after large theoretical caculations.
