Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

A Novel Naturally Sampled Space Vector Pulse Width Modulation Algorithm [PDF]

2009 International Workshop on Intelligent Systems and Applications, 2009
A novel algorithm for the naturally sampled SVPWM in overmodulation region is proposed in this paper, the comparison between naturally sampled SVPWM and conventional SVPWM in overmodulation region is carried out. It was proved that naturally sampled SVPWM could be used not only in under modulation but also in overmodulation region by the results of ...
