【Abstract】 The Ebers Moll (EM) model of transistors is improved by using Kirchhoffs law so as to characterize digital integrated transistors that have a four layer structure. By comparing the variation of the current flowing through each PN junction of transistors, the effects of parasite transistors in digital integrated transistors can be studied under different working states, especially under cut off state and saturation.更多还原
