This book discusses the theoretical foundations and design techniques needed to effectively design high-speed (multi-GS/s) and high-performance pipelined ADCs, which play a critical role in the signal chain of various systems. Readers will be walked through the design and analysis of pipelined ADCs and their topologies, and will learn both theoretical and practical design details that will enable them to explore and build these data converters. The author also presents details on various aspects of pipelined ADCs and their impact on the ADC speed and performance, with a focus on the input buffer and sampling network, the reference amplifier, comparators and their impact on ADC error rate and high-frequency performance, and mismatch estimation and correction.

Analog-to-digital converters (ADCs) are instrumental components in electronic systems. They serve as one of the interfaces between the analog world and the digital signal processing (DSP) algorithms that interpret the world. Almost every system we interact with requires such an interface. Used in applications ranging from communication systems to ultrasound machines, from security cameras to internet-of-things sensors, ADCs play a critical role in the complete signal chain, and are a ubiquitous element in our lives. The choice of ADC architecture depends on the target application and its specifications, and this book discusses one of those architectures—that of the pipelined ADC.

This book focuses solely on the pipelined ADC, an elegant architecture that addresses a large number of application needs. It is written for both the experienced engineer who would like to learn more about certain subtleties of pipelined ADCs, and for new engineers who would like to have a more in-depth perspective of what a pipelined ADC design entails.

This book does not cover all aspects of pipelined ADCs. There is rich research history on various topics in pipelined ADC design (such as on amplifier topologies, calibration algorithms, and noise analysis). As a result, I decided to not include some of these topics in this book (references are provided when these are mentioned). Even though these are all crucial elements of pipelined ADC design, there are other aspects that are much less frequently discussed and that also impact performance. These “second-order” considerations are the primary focus of this book.
