Components of Analog CMOS ICs

Abstract

This chapter aims to cover the fundamental aspects of integrated circuit (IC) components such as MOS transistors, resistors, capacitors, and inductors – discussing their physical properties, limitations, and their use in high-frequency circuit design. The IC design process is increasingly done with the help of computer-aided design tools using sophisticated design algorithms and detailed model parameter sets provided by IC manufacturers. Hence, the design engineers are prone to take the simulation results for granted without thinking about the complicated interactions among thousands of components and their parasitics. This chapter provides an in-depth understanding of the physical properties of components as well as their behaviors influencing the performance of analog circuits. The current-voltage relations of MOS transistors derived with a new approach under non-velocity saturated and velocity saturated conditions. The parasitics of MOS transistors and their geometry- and technology-related properties are discussed. The passive components are also summarized with their parasitics and their limits of physical realization.
