Analyze BJT band diagrams and understand current gain, base transport factor, and emitter injection efficiency
Discuss the Ebers–Moll coupled diode model, equivalent circuits, cutoff, saturation, and active regions
Develop the Gummel–Poon charge control model for second-order effects—Early effect, high-level injection
Study HBTs and other advanced BJTs
We begin this chapter with a qualitative discussion of charge transport in a bipolar junction transistor (BJT), to establish a sound physical understanding of its operation. Then we shall investigate carefully the charge distributions in the transistor and relate the three terminal currents to the physical characteristics of the device. ...
