− Figure 3.36 For Practice Prob. 3.11. † 3.9 APPLICATIONS: DC TRANSISTOR CIRCUITS | v v Most of us deal with electronic products on a routine basis and have
some experience with personal computers. A basic component for the
integrated circuits found in these electronics and computers is the active, three-terminal device known as the transistor. Understanding the
transistor is essential before an engineer can start an electronic circuit
Figure 3.37 depicts various kinds of transistors commercially available. There are two basic types of transistors: bipolar junction transistors (BJTs) and ﬁeld-effect transistors (FETs). Here, we consider only
the BJTs, which were the ﬁrst of the two and are...
