A spectro-temporal analysis of speech based on nonlinear operators
This paper proposes a spectro-temporal analysis based on a bank of cochlea filters in combinaison with a nonlinear operator for amplitude modulation enhancement in the medium and high frequency formants. The output of the spectrotemporal analysis is represented as a 3D image where it is possible to observe very short-term speech transitions and formant modulations. With such analysis, it is pos...
متن کاملDesign of a CMOS on-chip high voltage generator
In this paper, an original CMOS on-chip high voltage generator has been proposed. Having a hybrid charge pump structure, this high voltage generator benefits advantages of two charge pumps used and allows obtaining an output voltage that neither of the two charges pumps can reach individually. Simulation results show that an output voltage as high as 41V, which is inferior to the breakdown volt...
متن کاملHigh Voltage Cmos Technologies for Robust System-on-chip Design
In the past Smart Power System-on-Chip (SoC) products were almost exclusively designed on Bipolar-CMOS-DMOS (BCD) technologies. These products address applications as diverse as power management for mobile phones, motor drivers, printer head drivers, automotive bus transceivers and dataline drivers for high speed internet or Voice over IP (VoIP). The trend towards SoC design for lowering form f...
متن کاملOn chip Gaussian processing for high resolution CMOS image sensors
Spatial image processing chips, known as silicon retinas, are based on the architecture of vertebrate retina and can be mathematically represented as the Laplacian of Gaussian (LOG) and Difference of Gaussian (DOG). In this paper, attention has been paid on implementing a retina function through the LOG model. Previous implementations have used a hexagonal resistive mesh within the pixel array,...
متن کاملOn - chip pulse compression
A chip-based temporal compressor for shortening the duration of optical pulses has been developed by scientists in Japan. The scientists at Yokohama National University made their compressor from a silicon photonic crystal waveguide. Co-propagating slow light is used as a control pulse and serves to induce carrier plasma dispersion in the waveguide through two-photon absorption. The efficiency ...
