摘　　要：根据改进的超突变结变容管掺杂分布模型所得到的电容电压方程，对电容变化比较大时变容管的Ｃ－Ｖ曲线可能出现拐点这一现象进行了深入的研究，得出了产生拐点的条件，从而给出了理论上的解释．On the basis of capacitance-voltage characteristic equation obtained from an improved impurity profile model of hyperabrupt varactors, a thorough study has been conducted for the phenomenon for which the inflexion point may exist in C-V curves of varactors as the ratio of capacitance is large. The condition producing the inflexion point has been discussed and explained theoretically.
