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.

With the past few decade efforts on lithography and integrated-circuit (IC) technologies, very low-cost microsystems have been successfully developed for many different applications. The trend in wireless communications is toward creating a networkubiquitous era in the years to come. Many unprecedented opportunities and challenges, such as Design for multi-standardability and low-voltage (LV) compliance, are rapidly becoming the mainstream directions in wireless-IC research and development, given that the former can offer the best connectivity among different networks, while the latter can facilitate the technology migration into the sub-1-V nanoscale regimes for further cost and power reduction. Analog-Baseband Architecturees and Circuits presents architectural and circuit techniques for wireless transceivers to achieve multistandard and low-voltage compliance. The first part of the book reviews the physical layer specifications of modern wireless communication standards, presents the fundamental tradeoffs involved in transceiver architecture selection, and provides case studies of the state-of-the-art multistandard transceivers, where the key techniques reinforced are highlighted and discussed. A statistical summary (with 100+ references cited) of most used transmitter and receiver architectures for modern communication standards is provided. All the references are citied from the leading forums, i.e., ISSCC, CICC, VLSI and ESSCIRC, from 1997 to 2005. The second part focuses on the architectural design of multistandard transceivers. A coarse-RF fine-IF (two-step) channelselection technique is disclosed. It, through the reconfiguration of receiver and transmitter analog basebands, enables not only a relaxation of the RF frequency synthesizer’s and local oscillator’s design specifications, but also an efficient multistandard compliance by synthesizing the low-IF and zero-IF in the receiver; and the direct-up and two-step-up in the transmitter. The principle is demonstrated in few design examples. One of them is a system-in-a-package (SiP) receiver analog baseband for IEEE 802.11a/b/g WLAN. It not only has the two-step channel selection embedded, but also features a flexible-IF topology, a unique 3D-stack floorplan, and a particular design methodology for high testability and routability. The third part deals with the circuit design. In addition to the methodical description of many LV circuit techniques, 3 tailormade LV-robust functional blocks are presented. They include: 1) a double-quadrature-downconversion filter (DQDF) – it realizes concurrently clock-rate-defined IF reception, I/Q demodulation, IF channel selection and baseband filtering. 2) A switched-current-resistor (SCR) programmable-gain amplifier (PGA) – it offers a transient-free constant-bandwidth gain adjustment. 3) An inside-OpAmp dc-offset canceler – it saves the silicon area required for realizing a large time constant on chip while maximizing its highpass-pole switchability for fast dc-offset transient. The last part presents experimental results of the 3 tailor-made building blocks and a fully-integrated analog-baseband IC fabricated in a standard-VTH CMOS process. Previously untold on-/off-chip co-setup for both full-chip and building blocks measurements are described. Not only the building blocks have successfully extended the state-of-the-art boundary in terms of signal bandwidth and supply voltage, the analog-baseband IC has been so far the lowest-voltage-reported solution for IEEE 802.11a/b/g WLAN receivers.

This book provides readers with a description of state-of-the-art techniques to be used for ultra-low-power (ULP) and ultra-low-cost (ULC), short-range wireless receivers. Readers will learn what is required to deploy these receivers in short-range wireless sensor networks, which are proliferating widely to serve the internet of things (IoT) for “smart cities.” The authors address key challenges involved with the technology and the typical tradeoffs between ULP and ULC. Three design examples with advanced circuit techniques are described in order to address these trade-offs, which specially focus on cost minimization. These three techniques enable respectively, cascading of radio frequency (RF) and baseband (BB) circuits under an ultra-low-voltage (ULV) supply, cascoding of RF and BB circuits in current domain for current reuse, and a novel function-reuse receiver architecture, suitable for ULV and multi-band ULP applications such as the sub-GHz ZigBee. · Summarizes the state-of-the-art in ultra-low-power (ULP) wireless receivers; · Includes novel, ultra-low-power and ultra-low-cost (ULC), analog and RF circuit techniques--from concepts to practice; · Describes and demonstrates the first RF-to-baseband current-reuse 2.4GHz receiver and the first gain-boosted function-reuse sub-GHz receiver, with ULP and ULC in 65nm CMOS. .

Analog-to-Digital Converters (ADCs) play an important role in most modern signal processing and wireless communication systems where extensive signal manipulation is necessary to be performed by complicated digital signal processing (DSP) circuitry. This trend also creates the possibility of fabricating all functional blocks of a system in a single chip (System On Chip - SoC), with great reductions in cost, chip area and power consumption. However, this tendency places an increasing challenge, in terms of speed, resolution, power consumption, and noise performance, in the design of the front-end ADC which is usually the bottleneck of the whole system, especially under the unavoidable low supply-voltage imposed by technology scaling, as well as the requirement of battery operated portable devices. Generalized Low-Voltage Circuit Techniques for Very High-Speed Time-Interleaved Analog-to-Digital Converters will present new techniques tailored for low-voltage and high-speed Switched-Capacitor (SC) ADC with various design-specific considerations.
