Harvesting energy from environmental sources can extend wireless sensor network node lifetime beyond the limits of battery technology. However, the output power from an energy harvester is highly variable. We propose a domain-specific computational array which maximizes sensor performance by matching system power consumption to the available scavenged(More)
We present evidence for neutrons emanating from partially-deuterided titanium foils (TiD x) subjected to non-equilibrium conditions. 1 A previous paper presented data for complementary charged-particle emissions. Metal processing and establishing non-equilibrium conditions appear to be important keys to achieving significant nuclear-particle yields and(More)
Objective Obtain a position to develop energy efficient circuits, and systems. January 2006 – Present • Conducted an exploration of pulse width modulation circuitry for on-chip low power interconnect design in a sensor network processing node. Work culminated in a master's thesis and test chip fabricated in 0.25µm CMOS technology. • Participated in the(More)
Low power signal processing functionality is required for wireless sensor network nodes due to their limited battery life. Previously, we have proposed a reconfigurable array of DSP acceleration functional units for such a sensor node. The array maximizes operating life by matching system power consumption to available energy through power scalable(More)
A full-swing on-chip interconnect using pulse width modulation (PWM) was designed and fabricated in 0.25μm CMOS for application in a tiled signal processing array architecture targeting wireless sensor nodes. Measurements show a decrease in the worst case power of 7% over traditional binary signaling for 11.8mm long wires at 10Mbps throughput and 0.7V(More)
One of the most important design issues for battery operated multimedia applications is low energy consumption. This paper proposes an energy optimization technique for latency and quality constrained video applications in a multimedia gateway. We propose different queue creation and scheduling algorithms to dynamically change the energy/distortion factor(More)
