Overview of Logic CMOS Devices

Abstract

In this chapter, we provide a brief review of basic CMOS devices and device physics. We start by walking through the basic devices that are available in generic CMOS processes, covering rudimentary device physics that are of particular interests to the central theme of this book (including p–n junctions and gate oxide breakdown) and their effects on the design rules of non-logic active and passive devices. As power consumption has become the main barrier for IC design and applications, for example, in wearable ICs, it is useful to always keep in mind the fundamental factors affecting CMOS power consumption. We conclude with a brief analysis of power consumption of CMOS ICs.
