CHAPTER TWELVE TRANSISTOR CIRCUITS

In this chapter, MATLAB will be used to solve problems involving metaloxide semiconductor field effect and bipolar junction transistors. The general topics to be discussed in this chapter are dc model of BJT and MOSFET, biasing of discrete and integrated circuits, and frequency response of amplifiers. 12.1 BIPOLAR JUNCTION TRANSISTORS Bipolar junction transistor (BJT) consists of two pn junctions connected backto-back. The operation of the BJT depends on the flow of both majority and minority carriers. There are two types of BJT: npn and pnp transistors. The electronic symbols of the two
