Textbook in PDF format This book explores the rationale behind using incremental analog-to-digital converters (IADCs), delving into their theoretical principles, tradeoffs, and practical considerations in architectural and circuit design. The authors provide a general foundational knowledge, exploring the history of incremental operation and revising the working principle of free-running Delta-Sigma ADCs, in order to compare them with the incremental ADC. The IADC revises time- and frequency domain approaches to understand the incremental ADC as a periodically time-variant mixed-signal system. Various options for the reconstruction filter are revised together with system level design approaches and tools. The influence of non-idealities and countermeasures are analyzed and simulated. Enhanced architectures are finally explored and compared to give the reader a complete overview of the topic of Incremental ADCs
