CMOS Analog and Mixed-Signal Circuit Design

2	Devices An Overview

2.1      INTRODUCTION

Complementary Metal-Oxide Semiconductor (CMOS) technology continues to be the dominant technology for fabricating integrated circuits. This book will cover basic devices such as metal-oxide semiconductor field-effect transistor (MOSFET) with both long and short-channel operations. This topic is covered in one chapter solely to provide a MOSFET understanding to the readers. The understanding of MOSFET is very crucial in CMOS circuit design. Photo devices and other related devices are also discussed in this chapter. A new topic such as fitting ratio is included to discuss the “design transfer” approach. This approach is useful for practicing engineers.
