Power is a primary concern in modern circuits. Clock distribution networks, in particular, are an essential element of a synchronous digital circuit and a significant power consumer. Clock distribution networks are subject to clock skew due to process, voltage, and temperature (PVT) variations and load imbalances. A target skew between sequentially-adjacent registers can be obtained in a balanc...

Low-Power Architectural Design Methodologies by Paul Eric Landman Doctor of Philosophy in Engineering Electrical Engineering and Computer Sciences University of California at Berkeley Professor Jan M. Rabaey, Chair In recent years, power consumption has become a critical design concern for many VLSI systems. Nowhere is this more true than for portable, battery-operated applications, where power...

Designing systems for low power, or low power codesign, was not very much addressed as a whole by the current research. There has been considerable work on low power hardware, some on software power consumption and little on low power communication. This paper will present a motivation for addressing power consumption at system level together with an overview of the design methods for low power...

Motivated by emerging battery-operated applications that demand intensive computation in portable environments, techniques are investigated which reduce power consumption in CMOS digital circuits while maintaining computational throughput. Techniques for low-power operation are shown which use the lowest possible supply voltage coupled with architectural, logic style, circuit, and technology op...

As an increasing number of electronic systems are powered by batteries, battery life becomes a primary design consideration. Maximizing battery life requires system designers to develop an understanding of the capabilities and limitations of the batteries that power such systems, and to incorporate battery considerations into the system design process. Recent research has shown that, the amount...

The application of ultra-wideband (UWB) technology to low-cost short-range communications presents unique challenges to the communications engineer. The impact of the US FCC’s regulations and the characteristics of the low-power UWB propagation channels are explored, and their effects on UWB hardware design are illustrated. This tutorial introduction includes references to more detailed explora...

Wireless sensor networks are based on a large number of tiny sensor nodes, which collect various types of physical data. These sensors are typically energy-limited and low-power operation is an important design constraint. In this paper, we propose a novel routing and reporting scheme based on sample data similarities commonly observed in sensed data. Based on reliable transport protocols, the ...
