共源共栅电路对于驱动常开宽带隙器件非常有用，但必须正确理解开关过程才能优化其设计。此前对此很少有详细的考虑。本文提出了共源共栅开关过程的理想化数学描述，用于表明两个器件之间的杂散电感在开关中起着至关重要的作用。该理想化模型用于提出在不同应用中优化共源共栅性能的方法。
Cascode circuits are useful for driving normally-on wide-bandgap devices, but the switching process must be properly understood to optimise their design. Little detailed consideration has previously been given to this. This paper proposes an idealised mathematical description of the cascode switching process, which is used to show that the stray inductance between the two devices plays a critical role in switching. This idealised model is used to propose methods for optimising cascode performance in different applications.
