Creating Integrated Circuits That Can Generate Chaotic Signals
Researchers at Tokyo Institute of Technology have found a simple, yet highly versatile way to generate “chaotic signals” with various features. The technique consists of interconnecting three ring oscillators, effectively making them compete against each other, while controlling their respective strengths and their linkages. The resulting device is rather small and efficient, thus suitable for…
Magnetization Reversal Achieved at Room Temperature Using Only an Electric Field
Scientists at Tokyo Institute of Technology achieved magnetization reversal in cobalt-substituted bismuth ferrite by applying only an electric field. Such an effect had been sought after for over a decade in order to make new types of low-power-consumption magnetic memory devices. In the era of information technology revolution, electronics demand rapid evolution facilitated by greater…
