This paper provides an overview of research developments toward nanometer-scale electronic switching devices for use in building ultra-densely integrated electronic computers. Specifically, two classes of alternatives to the field-effect transistor are considered: 1) quantum-effect and single-electron solid-state devices and 2) molecular electronic devices. A taxonomy of devices in each class is provided, operational principles are described and compared for the various types of devices, and the literature about each is surveyed. This information is presented in nonmathematical terms intended for a general, technically interested readership

This paper addresses the current research in multi-standard wireless mixed-signal single -chip transceivers. Multi-standard refers to the capability to support various wireless standards and mixed-signal refers to both digital and analog circuitry on the same chip. The paper contains an indication and analysis of the problems associated with the integration of both RF and baseband circuits of wireless transceivers on a single die. The implementation technology is silicon which offers a high level of integration and a low cost which is desirable for large scale manufacturing. The trends in current research are listed and conclusions are made to what the prospects may be for the future. IINTRODUCTION I N recent years the developments in large-scale circuit integration have greatly facilitated an evolution of mobile radio communications throughout most of the world. New fabrication technologies have made portable equipment smaller, cheaper, and more reliable. This trend is expec...

This report (thesis) presents an architectural design methodology for computing systems suitable for a class of real-time applications, characterized by a large volume of periodic real-time data input at a high rate and vector operations on the real-time data. The proposed methodology incorporates into the architectural design the notion of resource sharing as well as techniques for satisfying timing requirements.
