C = C = ϵ {\displaystyle \epsilon _{Si}} j {\displaystyle C_{GDj}=A_{GD}{\frac {\epsilon _{Si}}{w_{GDj}}}}, C G {\displaystyle C_{GDj}\left(V_{GD}\right)=A_{GD}{\sqrt {\frac {q\epsilon _{Si}N}{2V_{GD}}}}}, 可以看出CGDj(以及CGD)的電容值會隨源極及汲極的電壓而改變。若電壓是增加,則電容也會增加。若MOSFET在導通態,CGDj短路,閘極對汲極電容等於CoxD,為一定值。, 因為源極的金屬化會覆蓋P井(如圖1),汲極和源極的端子會被PN结隔開,因此CDS即為PN结的電容,電容是非線性電容,可以用類似CGDj的公式求得。, MOSFET的晶元需要和和外部的電路連接,多半會用打線接合的方式連接到MOSFET的端子(目前也在研究其他的接方式)。接線中會有雜散電感,這不是專門針對MOSFET的技術,但若在高速切換下,會有很明顯的效應。雜散電感會使電流維持定值,在晶體關閉時會產生大電壓,因此會增加切換損。, National Institute of Advanced Industrial Science and Technology, Audio and video interfaces and connectors.
