In Chapter 24, we discussed two kinds of transistors—bipolar junction transistors (BJTs) and field effect transistors (FETs). The previous chapters have focused primarily on BJTs because they are, in fact, great at various tasks that are commonly considered “amplification.”

However, there are two amplification tasks for which BJTs are terribly suited—switching and logic circuits. Many people don’t think of amplification when they think of logic circuits, but, indeed, they do require amplification. Think about the memory of a computer (which ...
