This thesis describes a background-calibration technique that overcomes timing errors in time-interleaved analog-to-digital converters (ADCs) in a way that is almost independent of the user-provided ADC input signal. Additive dither is widely used to achieve signal-independent background calibration of many errors in data converters [1]. For example, this technique has been used to calibrate for gain mismatch in time-interleaved ADCs [2]. In most cases, however, binary dither has been used, and binary dither is not able to detect timing errors when the user-provided ADC input is zero or constant because timing errors do not produce amplitude errors when the ADC input is constant. This thesis presents a study of the use of a random ramp-based dither signal to calibrate for timing errors in time-interleaved ADCs. To demonstrate the dither-based timing calibration, a prototype 10-bit 500-MS/s 4-channel ADC was fabricated in 40-nm CMOS. With the proposed timing calibration, the Signal-to-Noise-and-Distortion Ratio (SNDR) is 50.1 dB with a user-provided input at 249 MHz while consuming 6.2 mW, giving a figure of merit (FoM) of 48.4 fJ/step. Disabling the ramp after the timing calibration converges improves the SNDR to 51 dB and reduces the power dissipation to 5.8 mW as well as the FoM to 39.8 fJ/step. [1] H. E.

Time-interleaved Analog-to-Digital Converters describes the research performed on low-power time-interleaved ADCs. A detailed theoretical analysis is made of the time-interleaved Track & Hold, since it must be capable of handling signals in the GHz range with little distortion, and minimal power consumption. Timing calibration is not attractive, therefore design techniques are presented which do not require timing calibration. The design of power efficient sub-ADCs is addressed with a theoretical analysis of a successive approximation converter and a pipeline converter. It turns out that the first can consume about 10 times less power than the latter, and this conclusion is supported by literature. Time-interleaved Analog-to-Digital Converters describes the design of a high performance time-interleaved ADC, with much attention for practical design aspects, aiming at both industry and research. Measurements show best-inclass performance with a sample-rate of 1.8 GS/s, 7.9 ENOBs and a power efficiency of 1 pJ/conversion-step.

This book is the first graduate-level textbook presenting a comprehensive treatment of Data Converters. The advancement of digital electronics urged the availability of a still missing support for teaching and self-learning analog-digital interfaces at many levels: the specification, the conversion methods and architectures, the circuit design and the testing. This book, after the necessary study of the background theoretical elements, covers aspects and provide elements for a deep and comprehensive knowledge. The breath and the level of details of topics is enhanced by introductory material in each chapter and the use of many examples, most of them in the form of computer behavioral simulations. The examples and the end-of-chapter problems help in understanding and favor self-practice using tools that are effective for training and for design activity. Data Converters is a textbook that is also essential for engineering professionals as it was written for responding to a shortage of organically organized material on the topic. The book assumes a solid background in analog and digital circuits as well as a working knowledge of simulation tools for circuit and behavioral analysis. A background on statistical analysis is also helpful, though not strictly necessary. Coverage of all the basic elements essential for a clear understanding of sampling, quantization, noise in sampled-data systems and mathematical tools for sampled-data linear systems Comprehensive definition of the parameters used to specify data converters and necessary for understanding product data sheets Coverage of all the architectures used in Nyquist-rate data converters and detailed study of features, limits and design techniques Detailed study of oversampled and Sigma-Delta converters with simulation examples and use of spectra and histograms for a clear understanding of features and limit if the noise shaping Coverage of digital correction and calibration techniques for enhancing performances Use of theory and intuitive views to explain circuits and systems operation and limits Coverage of testing methods and description of the data processing used for testing and characterization Extensive use of Simulink and Matlab in examples and problem sets to assist reader comprehension and favor deeper study
