Preface

Device-level modeling and synthesis of high-performance pipeline ADCs Digital computing and signal processing are present in most current communications systems. The proliferation of these systems, compared with their analog counterparts, is a result of their robustness to supply and processing variations, their low sensitivity to noise and, above all, the improvements in their technological scaling [1–5]. These properties have made the design and test automation of such systems easier, favouring the development of Computer-Aided Design (CAD) tools and automatized methodologies. In spite of the benefits of digital processing, a communications system cannot be fully digital as the actual signals are inherently analog and as a result, there is a need for circuits which can interface with the digital world. Analog-to-Digital Converters (ADCs), which acquire and digitize the signal, fall into the category of circuits required. As Fig. 1 shows, numerous approaches can be found, depending on the field of application of the converter. The design of these analog circuits is a major challenge for designers due to rapidly-evolving digital systems, which require increasingly accurate and fast converters, while the current trend to integrate them into adverse digital technologies is also a contributing factor. Hence the importance of dev
