Chapter 6. Using Transistors to Build Logic Gates

NMOS, PMOS, and CMOS

There are several different families of transistors available to designers and, although the actual implementations vary, each can be used to construct primitive logic gates. This book concentrates on the enhancement-mode Metal-Oxide Semiconductor Field-Effect Transistors (MOSFETs) introduced in Chapter 4: Semiconductors (Diodes and Transistors). There are two reasons for this. First, their symbols, construction, and operation are easier to understand than are their Bipolar Junction Transistor (BJT) cousins. Second, enhancement-mode MOSFETs are the most widely used transistors in the world, finding application in both analog and digital circuits, especially in today’s digital ...
