| Research Abstract |
Aiming at the development of noise-driven information processing systems on possible nano-scale semiconductor devices, the following systems have been developed: (i) weak-signal detector based on stochastic resonance, (ii) an analog-to-digital converter that utilized noise and fluctuations, (iii) fast signal transmission utilizing mismatches of semiconductor devices, (iv) noise-induced phase synchronization among subthreshold CMOS oscillators, (v) ultra-low-power logic memory cells utilizing noise and fluctuations, and (vi) brain-inspired information processing circuits that utilized noises. Molecular devices for (i), (iii) and (v) have also been developed with group A04, and we could observe expected operations of the molecular devices for (i). For the rest items [(ii), (iv), and (v)], we evaluated the model on nano semiconductor devices, and could observe desired dynamical operations.
