Adaptive radio transceivers require a comprehensive theoretical framework in order to optimize their performance. Adaptive Low-Power Circuits for Wireless Communications provides this framework with a discussion of joint optimization of Noise Figure and Input Intercept Point in receiver systems. Original techniques to optimize voltage controlled oscillators and low-noise amplifiers to minimize their power consumption while maintaining adequate system performance are also provided. The experimental results presented at the end of the book confirm the utility of the proposed techniques.

By the end of this decade, a 4G wireless terminal will be available that provides high quality multimedia, personalized services, and ubiquitous multi-standard broadband connectivity with a reasonable power consumption. In this context, a multi-band transceiver is needed that provides a high-level of programmability while keeping low design complexity and costs. Software Defined Radio (SDR) is the most promising technology to implement such a terminal as it enables multi-mode reception by tuning to any frequency band, by selecting any channel bandwidth, and by detecting any modulation. Baseband Analog Circuits for Software Defined Radio aims to describe the transition towards a Software Radio from the analog design perspective. As the original idea of a "full-digital" Software Radio is far from the state-of-art, an analog front-end is still needed to achieve a feasible implementation. Most of the existent front-end architectures are explored from the flexibility point of view. A complete overview of the actual state-of-art for reconfigurable transceivers is given in detail, focusing on the challenges imposed by flexibility in analog design. As far as the design of adaptive analog circuits is concerned, specifications like bandwidth, gain, noise, resolution and linearity should be programmable. The development of circuit topologies and architectures that can be easily reconfigured while providing a near optimal power/performance trade-offs is a key challenge. In this book, we tackle this challenge mainly for baseband analog circuits, i.e. amplifiers and filters, proposing efficient solutions that provide a high level of programmability. Measurements results validate the design strategies.

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.

Realizing maximum performance from high bit-rate and RF circuits requires close attention to IC technology, circuit-to-circuit interconnections (i.e., the ‘interconnect’) and circuit design. This detailed book covers each of these topics from theory to practice, with sufficient detail to help you produce circuits that are ‘first-time right’. Many practical circuit examples are included to demonstrate the interplay between technology, interconnect and circuit design.

As the miniaturization of semiconductor technology continues, electronic s- tems on chips o?er a more extensive and more complex functionality with better performance, higher frequencies and less power consumption. Whereas digital designers can take full advantage of the availability of design auto- tiontoolstobuildhugesystems,thelackofsupportbycomputerprogramsfor di?erent abstraction levels makes analog design a time-consuming handcraft which limits the possibilities to implement large systems. Various approaches for?ndingoptimalvaluesfortheparametersofanalogcells,likeopamps,have been investigated since the mid-1980s, and they have made their entrance in commercial applications. However, a larger impact on the performance is - pected if tools are developed which operate on a higher abstraction level and consider multiple architectural choices to realize a particular functionality. In this book, the opportunities, conditions, problems, solutions and systematic methodologies for this new generation of analog CAD tools are examined. Theoutlineofthisbookisasfollows. Inthe?rstpart,thecharacteristicsof the analog design process are systematically analyzed and several approaches for automated analog synthesis are summarized. Comparison of their prop- ties with the requirements for high-level synthesis of analog and mixed-signal systems results in a new design paradigm: the high-level design ?ow based on generic behavior. This design approach involves a modeling strategy using generic behavioral models and a synthesis strategy leading to the exploration of a heterogeneous design space containing di?erent architectures. The modeling strategy is further elaborated in Part II.

As the requirements for low power consumption and very small physical dimensions in portable, wearable and implantable medical devices are calling for integrated circuit design techniques using MOSFETs operating in the subthreshold regime, this book first revisits some well-known circuit techniques that use CMOS devices biased in subthreshold in order to establish nanopower integrated circuit designs. Based on the these findings, this book shows the development of a class-AB current-mode sample-and-hold circuit with an order of magnitude improvement in its figure of merit compared to other state-of-the-art designs. Also, the concepts and design procedures of 1) single-branch filters 2) follower-integrator-based lowpass filters and 3) modular transconductance reduction techniques for very low frequency filters are presented. Finally, to serve the requirement of a very large signal swing in an energy-based action potential detector, a nanopower class-AB current-mode analog multiplier is designed to handle input current amplitudes of more than 10 times the bias current of the multiplier circuit. The invented filter circuits have been fabricated in a standard 0.18 μ CMOS process in order to verify our circuit concepts and design procedures. Their experimental results are reported.

The low cost and direct digital output of CMOS smart temperature sensors are important advantages compared to conventional temperature sensors. This book addresses the main problem that nevertheless prevents widespread - plication of CMOS smart temperature sensors: their relatively poor absolute accuracy. Several new techniques are introduced to improve this accuracy. The effectiveness of these techniques is demonstrated using three prototypes. ? The ?nal prototype achieves an inaccuracy of±0.1 C over the military t- perature range, which is a signi?cant improvement in the state of the art. Since smart temperature sensors have been the subject of academic and industrial research for more than two decades, an overview of existing knowledge and techniques is also provided throughout the book. Inthisintroductorychapter,themotivationandobjectivesofthisworkare- scribed. ThisisfollowedbyareviewofthebasicoperatingprinciplesofCMOS smart temperature sensors, and a brief overview of previous work. The ch- lenges are then described that need to be met in order to improve the accuracy of CMOS smart temperature sensors while maintaining their cost advantage. Finally, the structure of the rest of the book is introduced.
