The prospect of initializing a network-ubiquitous society in the years to come has led to the development of multistandard-compliant wireless transceivers for seamless roaming among multiple networks. To ensure a commercial success of such a development, the manufacturing cost and power consumption of the system chips have to be minimized. The use of an advanced technology and a high level of integration have continued to be the most effective ways for cost and power minimization, given that wireless chips integrate large amounts of digital logic for computation. Regrettably, entering into the nanoelectronics era, the thinner transistor gate oxide implicates great challenges in the design of the analog front-ends. While a low-voltage supply is imposed to maintain device reliability, a relatively large threshold voltage is also necessitated to limit the leakage current. Thus, transceiver architectures and circuits which will befit future full integration of multistandard wireless transceivers in sub-1V nanoscale CMOS processes must be highly reconfigurable and robustly operational underneath a l- voltage supply. This book presents novel analog-baseband architectures and circuits that help realizing multistandard and low-voltage wireless transceivers. The main contents are presented from Chapter 2 to Chapter 6, as pictorially outlined in Figure 1. Chapter 1 overviews the current wireless-IC developments and presents the motivation and research objectives of this book. xi xii Preface Figure 1.
