Book Description
This book discusses a number of challenges faced by designers of wireless receivers, given complications caused by the shrinking of electronic and mobile devices circuitry into ever-smaller sizes and the resulting complications on the manufacturability, production yield, and the end price of the products. The authors describe the impact of process technology on the performance of the end product and equip RF designers with countermeasures to cope with such problems. The mechanisms by which these problems arise are analyzed in detail and novel solutions are provided, including design guidelines for receivers with robustness to process variations and details of circuit blocks that obtain the required performance level. Describes RF receiver frontends and their building blocks from a system- and circuit-level perspective; Provides system-level analysis of a generic RF receiver frontend with robustness to process variations; Includes details of CMOS circuit design at 60GHz and reconfigurable circuits at 60GHz; Covers millimeter-wave circuit design with robustness to process variations.

Book Description
This book describes several techniques to address variation-related design challenges for analog blocks in mixed-signal systems-on-chip. The methods presented are results from recent research works involving receiver front-end circuits, baseband filter linearization, and data conversion. These circuit-level techniques are described, with their relationships to emerging system-level calibration approaches, to tune the performances of analog circuits with digital assistance or control. Coverage also includes a strategy to utilize on-chip temperature sensors to measure the signal power and linearity characteristics of analog/RF circuits, as demonstrated by test chip measurements. Describes a variety of variation-tolerant analog circuit design examples, including from RF front-ends, high-performance ADCs and baseband filters; Includes built-in testing techniques, linked to current industrial trends; Balances digitally-assisted performance tuning with analog performance tuning and mismatch reduction approaches; Describes theoretical concepts as well as experimental results for test chips designed with variation-aware techniques.

Book Description
Design considerations for low-power operations and robustness with respect to variations typically impose contradictory requirements. Low-power design techniques such as voltage scaling, dual-threshold assignment and gate sizing can have large negative impact on parametric yield under process variations. This book focuses on circuit/architectural design techniques for achieving low power operation under parameter variations. We consider both logic and memory design aspects and cover modeling and analysis, as well as design methodology to achieve simultaneously low power and variation tolerance, while minimizing design overhead. This book will discuss current industrial practices and emerging challenges at future technology nodes.

Book Description
This book discusses the trade-offs involved in designing direct RF digitization receivers for the radio frequency and digital signal processing domains. A system-level framework is developed, quantifying the relevant impairments of the signal processing chain, through a comprehensive system-level analysis. Special focus is given to noise analysis (thermal noise, quantization noise, saturation noise, signal-dependent noise), broadband non-linear distortion analysis, including the impact of the sampling strategy (low-pass, band-pass), analysis of time-interleaved ADC channel mismatches, sampling clock purity and digital channel selection. The system-level framework described is applied to the design of a cable multi-channel RF direct digitization receiver. An optimum RF signal conditioning, and some algorithms (automatic gain control loop, RF front-end amplitude equalization control loop) are used to relax the requirements of a 2.7GHz 11-bit ADC. A two-chip implementation is presented, using BiCMOS and 65nm CMOS processes, together with the block and system-level measurement results. Readers will benefit from the techniques presented, which are highly competitive, both in terms of cost and RF performance, while drastically reducing power consumption.

Book Description
"The continuing trends of scaling in the CMOS industry have, inevitably, been accompanied by an ever-increasing array of process faults and fabrication complexities. The relentless march towards miniaturization and massive integration, in addition to increasing operating frequencies has resulted in increasing concerns about the reliability of integrated RF front-ends. Couples with rising cost per chip, the fault-tolerant paradigm has become pertinent in the RFIC domain. Two main reasons have contributed to the fact that fault-tolerant solutions for circuits that operate in the GHz domain have not been realized so far. First, GHz signals are extremely sensitive to higher-order effects such as stray pick-ups, interference, package & on-chip parasitics, etc. Secondly, the use of passives, especially inductors, in the feedback path poses huge area overheads, in addition to a slew of instability problems due to wide variations and soft faults. Hence traditional fault-tolerance methods used in digital and low frequency analog circuits cannot be applied in the RF domain. This work presents a unique methodology to achieve fault-tolerance in RF circuits through dynamic sensing and on-chip self-correction, along with the development of robust algorithms. This technique is minimally intrusive and is transparent during 'normal' use of the circuit. It is characterized by low area and power overheads, does not need any off-chip computing or DSP cores, and is characterized by self-correction times in the range of a few hundreds of microseconds. It compares very well with existing commercial RF test solutions that use DSP cores and require hundreds of milliseconds. The methodology is demonstrated on a LNA, since it is critical for the performance of the entire front-end. It is validated with simulation and fabrication results of the system designed in IBM 0.25 um CMOS 6RF process"--Abstract.
