Inductive Noise Reduction at the Architectural Level
A methodology for reducing ground bounce in typical microprocessors and image processing architectures has been described. As we approach Gigascale Integration, chip power consumption is becoming a critical system parameter. Deactivating idle units provides needed reductions in power consumption. However, it introduces inductive noise that can limit voltage scaling. The paper introduces an arch...
متن کاملdesign of digital geo-electrical equipment and its application on noise level reduction
electrical resistivity survey is used to explore subsurface layers in hydrology, geology, mining, geotechnical and environmental investigations. the resistivity measurements are normally made by injecting current into the ground through two current electrodes, and measuring the resulting voltage difference at two potential electrodes. electrical resistivity is a function of injection current, m...
متن کاملDigital Frequency Synthesizer
This paper presents a novel algorithm and architecture for digital frequency synthesis DFS . It is based on a simple difference equation. Simulation results show that the proposed DFS algorithm is preferable to the conventional phase-locked-loop frequency synthesizer and the direct digital frequency synthesizer in terms of the spurious-free dynamic range SFDR and the peak-signalto-noise ratio P...
متن کاملAdaptive Optimum Notch Filter for Periodic Noise Reduction in Digital Images
Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...
متن کاملLocal Oscillator Uncorrelated Phase Noise Analysis for Millimeter-wave Passive Imager Bhu-2d Frequency Synthesizer
In this paper, a nontrivial local oscillator uncorrelated phase noise analysis is proposed for frequency synthesizer of a passive millimeter-wave Synthetic Aperture Interferometric Radiometer (SAIR) imager BHU-2D designed for concealed weapon detections on human bodies with high imaging rates. The frequency synthesizer provides local oscillator signals for both millimeter-wave front-ends and in...
