Basic MOS Device Physics

1.1 Introduction

This chapter focuses on the fundamental aspects of metal-oxide semiconductor

(MOS) device behavior that are of immediate relevance to practical integrated circuit

(IC) design. It is intended as a review of basic principles rather than an in-depth

treatment of advanced topics.

Chapter Outline

This chapter is organized as follows. Section 1.2 describes the fundamental

aspects of MOS transistors. The basic properties of MOS switches are discussed

in Section 1.3. The behavior of the MOS device as a capacitor is discussed in Section

1.4.
