We propose dynamic resistive threshold-logic (DRTL) design based on non-volatile resistive memory. A threshold logic gate (TLG) performs summation of multiple inputs multiplied by a fixed set of weights and compares the sum with a threshold. DRTL employs resistive memory elements to implement the weights and the thresholds, while a compact dynamic CMOS latch is used for the comparison operation...

This work shows the possibility to exploit piezoelectric transformers (PTs) for implementing step-up oscillators for ultra-low DC voltage energy harvesting (EH) applications. Oscillation is achieved by coupling a common source stage made up of nchannel JFETs with a piezoelectric transformer acting like a high gain notch filter. A voltage doubler is used to store energy in a capacitor. A mathema...

Wireless networks are often very lightly used. Some wireless networks, most notably sensor networks, are also energyconstrained – that is, the period of time during which the network is operational depends on battery lifetime. We have designed and simulated a novel design for a mobile ad hoc network with a low offered load (of approximately 1% average loading) that uses dramatically less (often...

This article presents an ultra-low-power parallel computing platform and its system-on-chip (SoC) embodiment, targeting a wide range of emerging near-sensor processing tasks for Internet of Things (IoT) applications. The proposed SoC achieves 193 million operations per second (MOPS) per mW at 162 MOPS (32 bits), improving the first-generation Parallel Ultra-Low-Power (PULP) architecture by 6.4 ...

in the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized aa6061 aluminum alloy produced by equal channel angular pressing (ecap) process were investigated. the grain refinement after two passes of ecap significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. however, the improvement of low cycle fati...

in this study an ultra-broad band, low-power, and high-gain cmos distributed amplifier (cmos-da) utilizing a new gain-cell based on the inductively peaking cascaded structure is presented. it is created bycascading of inductively coupled common-source (cs) stage and regulated cascode configuration (rgc).the proposed three-stage da is simulated in 0.13 μm cmos process. it achieves flat and high ...

background: the comparison between voluntary and automatic contraction of deep abdominal muscles in patients with nonspecific low back pain (nlbp) may justify being the best treat for them. the aim of this case-controlled study was to compare changes in the thickness of the transverses abdomin is (tra) and internal oblique (io) muscles during the abdominal drawing-in maneuver (adim) and the act...
