A conduction model consisting of two parallel resistances from a highly conductive filament region and a uniform leakage oxide region is proposed in this brief to represent the current conduction in the filament-type switching resistive random access memory cell. Low-frequency noise analysis of current fluctuation at different resistance states has been employed to verify its efficiency. It is found...
We present an experimental analysis on a photonic temperature sensor based on microring resonators, and we show that the sensitivity can be better than 40μK, which is limited by technical noise.
In real-time, it is highly essential to have an autonomous translator that can process the images and recognize the signs very fast at the speed of streaming images. In this paper, architecture is being proposed using the neural networks identification and tracking to translate the sign language to a voice/text format. Introduction of Point of Interest (POI) and track point provides novelty and reduces...
The analysis and the design of the power delivery network (PDN) is crucial in the real world of high-speed and high-performance on-board systems. In this context, the cavity model (where facing portions of power bus are considered electromagnetic resonant cavities) can be used to study the generation and propagation of noise. Given a real-world board's layout, one of the primary requirements for the...
Signal vias are often used to move a signal from one PCB layer to another. As a result, these vias can penetrate power/ground plane pair and cause noise coupling (crosstalk) between signal and power/ground nets. This paper studies the noise coupling mechanism using a segmentation approach combined with a via capacitance model and a plane-pair cavity model. Noise coupling from signal to power/ground,...
Due to the increase in board density, routing traces on different layers becomes a widely used strategy. Through-hole vias are often used to connect these traces. Those vias that penetrate power/ground plane pairs could cause noise coupling between signal and power/ground nets. At the same time, the need for clean signal transmitted to receivers results in a wide use of differential signals. This...
A closed-form expression for via barrel-plate capacitances is derived. This results in a more accurate equivalent circuit model for decoupling capacitors including both parasitic inductances and via capacitances. Multilayer power distribution network (PDN) are then analyzed by incorporating the circuit models of both vias and parallel plane pair. Circuit simulator is used to evaluate the coupling...
We report observation of enhanced correlation, wavelength shifting, and spectral broadening of the twin beams in a parametric amplification with a gain greater than 30 dB in a 1.7 m microstructure fiber.
