Analog-Digital Interfaces

Abstract

In this chapter, we address interfacing high-frequency analog components with corresponding digital processing blocks, using data converters. Instead of considering specific system architectures, the main aspects of system design are presented with a generic approach. The key performance metrics for data converters are presented, and the most commonly used circuit architectures are presented, discussing their relative advantages and limitations. Flash, pipelined, and SAR ADCs are briefly introduced. The main purpose of this chapter is to draw attention to key issues that must be taken into account when combining analog and digital building blocks.
