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 Architectures and Circuits reviews the fundamentals and studies the state-of-the-art multistandard transceivers before describing novel architectural and circuit techniques for implementing multimode and wideband (tens of MHz) baseband analog front-ends under low-voltage constraints. Techniques developed on architecture level for efficient system-in-package (SiP) integration, testability and multi-standardability; and on circuit level for reducing the required supply voltage, power and area, are generally applicable for most wireless systems, and are somewhat independent to technology scaling. Experimental 1-V baseband building blocks (i.e., double-quadrature-downconversion filter, programmable-gain amplifier and dc-offset canceler) and a 1-V fully-integrated receiver analog-baseband chain for IEEE 802.11a/b/g WLAN validate the techniques. The implementations are all in standard-VTH CMOS process, and no voltage boosting is required at any node.
