Wireless devices in both office and home are playing a significant role in today's communication system. The most known communication gadgets include cellular telephone and wireless local area network (WLAN) peripherals. Wireless connectivity products main target is to provide d…
The Super- Regenerative Reception concept was developed in the early 1900s. The evolution of Heterodyne Reception has forced it into oblivion. However, recent research and development has emphasized its use in short distance and low power wireless applications. The results indic…
Wireless sensor networks have the potential to impact society through applications from environmental and health monitoring, to military surveillance. Network nodes are designed for extremely long lifetimes, and often rely on energy harvesting or scavenging devices for power, as…
While improving circuit's speed and reducing its area have been the primary figure of merits in digital VLSI design, more efforts are now spent on minimizing power dissipation. This is becoming equally true for both high-performance chips, such as microprocessors, to reduce cool…
One special type of memory use for high speed address lookup in router or cache address lookup in a processor is Content Addressable Memory (CAM). CAM can also be used in pattern recognition applications where a unique pattern needs to be determined if a match is found. CAM has …
There has been a dramatic increase in wireless awareness among the user community in the past five years. The 2.4-GHz Industrial, Scientific and Medical (ISM) band is being used for a diverse range of applications due to the following reasons. It is the only unlicensed band appr…
Power dissipation in CMOS devices has become one of the major challenges for scaling in the recent years. In fact, it has been suggested that the scaling may stop long before we reach any fundamental barriers because of our inability to remove the heat generated in these devices…
The explosive growth of battery operated devices has made low-power design a priority in recent years. Moreover, embedded SRAM units have become an important block in modern SoCs. The increasing number of transistor count in the SRAM units and the surging leakage current of the …
Bio-electric signals convey information and phenomenon of the physiological activities of organisms, such as gene, protein sequences, neural, and cardiac rhythms. Various types of bio-electrical signals are extensively used for diagnostics as well as therapeutic interventions. B…
High-performance CPUs commonly deployed in data-centers accumulate a significant amount of energy and run in the millions of kilowatts per year. This family of CPUs can highly benefit from low power techniques that do not negatively impact performance. This work addresses the is…
Advanced CMOS technology exhibits increasing variations in performance, power consumption and reliability parameters. These variations led to extensive overdesigning and increased power consumption to guarantee 100% reliable operation. However, with the continuous shrinking of d…
Power consumption in computing today has lead the industry towards energy efficient computing. As transistor technology shrinks, new techniques have to be developed to keep leakage current, the dominant portion of overall power consumption, to a minimum. Due to the large amount …
