1. 1 Power-dissipation trends in CMOS circuits Shrinking device geometry, growing chip area and increased data-processing speed performance are technological trends in the integrated circuit industry to enlarge chip functionality. Already in 1965 Gordon Moore predicted that the total number of devices on a chip would double every year until the 1970s and every 24 months in the 1980s. This prediction is widely known as "Moore's Law" and eventually culminated in the Semiconductor Industry Association (SIA) technology road map [1]. The SIA road map has been a guide for the in dustry leading them to continued wafer and die size growth, increased transistor density and operating frequencies, and defect density reduction. To mention a few numbers; the die size increased 7% per year, the smallest feature sizes decreased 30% and the operating frequencies doubled every two years. As a consequence of these trends both the number of transistors and the power dissi pation per unit area increase.In the near future the maximum power dissipation per unit area will be reached. Down-scaling of the supply voltage is not only the most effective way to reduce power dissipation in general it also is a necessary precondition to ensure device reliability by reducing electrical fields and device temperature, to prevent device degradation. A draw-back of this solution is an increased signal propa gation delay, which results in a lower data-processing speed performance.

Low Power Design in Deep Submicron Electronics deals with the different aspects of low power design for deep submicron electronics at all levels of abstraction from system level to circuit level and technology. Its objective is to guide industrial and academic engineers and researchers in the selection of methods, technologies and tools and to provide a baseline for further developments. Furthermore the book has been written to serve as a textbook for postgraduate student courses. In order to achieve both goals, it is structured into different chapters each of which addresses a different phase of the design, a particular level of abstraction, a unique design style or technology. These design-related chapters are amended by motivations in Chapter 2, which presents visions both of future low power applications and technology advancements, and by some advanced case studies in Chapter 9. From the Foreword: `... This global nature of design for low power was well understood by Wolfgang Nebel and Jean Mermet when organizing the NATO workshop which is the origin of the book. They invited the best experts in the field to cover all aspects of low power design. As a result the chapters in this book are covering deep-submicron CMOS digital system design for low power in a systematic way from process technology all the way up to software design and embedded software systems. Low Power Design in Deep Submicron Electronics is an excellent guide for the practicing engineer, the researcher and the student interested in this crucial aspect of actual CMOS design. It contains about a thousand references to all aspects of the recent five years of feverish activity in this exciting aspect of design.' Hugo de Man Professor, K.U.

In the deep sub-micron regime, the power consumption has become one of the most important issues for competitive design of digital circuits. Due to dramatically increasing leakage currents, the power consumption does not take advantage of technology scaling as before. State-of-art power reduction techniques like the use of multiple supply and threshold voltages, transistor stack forcing and power gating are discussed with respect to implementation and power saving capability. Focus is given especially on technology dependencies, process variations and technology scaling. Design and implementation issues are discussed with respect to the trade-off between power reduction, performance degradation, and system level constraints. A complete top-down design flow is demonstrated for power gating techniques introducing new design methodologies for the switch sizing task and circuit blocks for data-retention and block activation. The leakage reduction ratio and the minimum power-down time are introduced as figures of merit to describe the power gating technique on system level and give a relation to physical circuit parameters. Power Management of Digital Circuits in Deep Sub-Micron CMOS Technologies mainly deals with circuit design but also addresses the interface between circuit and system level design on the one side and between circuit and physical design on the other side.

Design exibility and power consumption in addition to the cost, have always been the most important issues in design of integrated circuits (ICs), and are the main concerns of this research, as well. Energy Consumptions: Power dissipation (P ) and energy consumption are - diss pecially importantwhen there is a limited amountof power budgetor limited source of energy. Very common examples are portable systems where the battery life time depends on system power consumption. Many different techniques have been - veloped to reduce or manage the circuit power consumption in this type of systems. Ultra-low power (ULP) applications are another examples where power dissipation is the primary design issue. In such applications, the power budget is so restricted that very special circuit and system level design techniquesare needed to satisfy the requirements. Circuits employed in applications such as wireless sensor networks (WSN), wearable battery powered systems [1], and implantable circuits for biol- ical applications need to consume very low amount of power such that the entire system can survive for a very long time without the need for changingor recharging battery[2–4]. Using newpowersupplytechniquessuchas energyharvesting[5]and printable batteries [6], is another reason for reducing power dissipation. Devel- ing special design techniques for implementing low power circuits [7–9], as well as dynamic power management (DPM) schemes [10] are the two main approaches to control the system power consumption. Design Flexibility: Design exibility is the other important issue in modern in- grated systems.

Design of Very High-Frequency Multirate Switched-Capacitor Circuits presents the theory and the corresponding CMOS implementation of the novel multirate sampled-data analog interpolation technique which has its great potential on very high-frequency analog frond-end filtering due to its inherent dual advantage of reducing the speed of data-converters and DSP core together with the specification relaxation of the post continuous-time filtering. This technique completely eliminates the traditional phenomenon of sampled-and-hold frequency-shaping at the lower input sampling rate. Also, in order to tackle physical IC imperfections at very high frequency, the state-of-the-art circuit design and layout techniques for high-speed Switched-Capacitor (SC) circuits are comprehensively discussed: -Optimum circuit architecture tradeoff analysis -Simple speed and power trade-off analysis of active elements -High-order filtering response accuracy with respect to capacitor-ratio mismatches -Time-interleaved effect with respect to gain and offset mismatch -Time-interleaved effect with respect to timing-skew and random jitter with non-uniformly holding -Stage noise analysis and allocation scheme -Substrate and supply noise reduction -Gain-and offset-compensation techniques -High-bandwidth low-power amplifier design and layout -Very low timing-skew multiphase generation Two tailor-made optimum design examples in CMOS are presented. The first one achieves a 3-stage 8-fold SC interpolating filter with 5.5MHz bandwidth and 108MHz output sampling rate for a NTSC/PAL CCIR 601 digital video at 3 V. Another is a 15-tap 57MHz SC FIR bandpass interpolating filter with 4-fold sampling rate increase to 320MHz and the first-time embedded frequency band up-translation for DDFS system at 2.5V. The corresponding chip prototype achieves so far the highest operating frequency, highest filter order and highest center frequency with highest dynamic range under the lowest supply voltage when compared to the previously reported high-frequency SC filters in CMOS.

In the market of wireless communication, high data-rate transmission and high spectral efficiency have been the trend. The IEEE 802.11 a/g standards working at 5GHz/2.4GHz ISM bands can support data rate up to 54Mbits/s using OFDM modulation. The newly proposed 802.11n technology now uses 64-QAM to achieve higher spectral efficiency. The DVB and many other systems will also use QAM for its data transmission. The cost of achieving this higher spectral efficiency using higher order QAM is that the transmitter and receiver requires a higher signal to noise ratio (SNR) with the same level of error rate performance (relative to a baseline BPSK, QPSK and other systems). One of the dominant vectors on SNR degradation is I/Q image rejection (I/Q gains and phases imbalance). There are a lot of factors that degrade the matching of gains and phases between I/Q signals: the instinct layout mismatch, the random mismatch of the devices, the different temperatures over the I/Q signal paths. IQ Calibration Techniques For CMOS Radio Transceivers describes a fully-analog compensation technique without baseband circuitry to control the calibration process. This book will use an 802.11g transceiver design as an example to give a detailed description on the I/Q gains and phases imbalance auto-calibration mechanism.
