Abstract (in Japanese) (See Japanese page) 
(in English) This report aims at the development of on-chip distributed clock sources on synchronous digital VLSIs. We focused attention on noise-induced phase synchronization among independent nonlinear oscillators (neurons). When the neurons are regarded as electronic oscillator circuits whose phases are synchronized by noises, one can regard the circuits as distributed clock-skew-free oscillators on VLSIs. First, we review theoretical analysis of noise-induced phase synchronization where variables of oscillator dynamics are described in terms of phases, and the transient phase difference is decreased by applying common noises, because of the negative Lyapunov exponent of the phase dynamics. We then propose an analog oscillator circuit which is able to accept weak photo-current noises, and demonstrate phase synchronization among the oscillators by SPICE simulations.
