摘要
This paper examines the impact of quasi-ballistic transport (QBT) on bipolar transistor (BJT) intrinsic terminal current noise by analytically solving the general 3-D minority carrier noise transport equation using Hansen's nonhomogenous boundary conditions with extensions to include injection noise. Transistor noises are further expressed in Y-parameters, as was done in the widely used van Vliet model, with extra corrections accounting for QBT. For 10-nm base width of BJTs without base built-in field, while QBT is significant in affecting I-C, S-ic is shown to be less than but close to the classic 2(q) I-C.
