WebEE 436 BJT — Early effect – 7 To reduce the base-width modulation effect, we need to have most of the base-collector depletion width occurring on the collector side of the junction. In order to do that, we need N DC < N AB. In a typical BJT, the “doping rank” is: N DE > N AB > N DC. Even though the BJT appears to be a symmetric sandwich ...
