| Research Abstract |
Pulse-coupled phase oscillator network systems that implement time-domain information processing using timing of spike pulses mimicking information processing architecture in the brain were designed and developed using a CMOS integrated circuit technology. First, integrated circuits that implement coupled systems of several oscillators were fabricated and the relationship between circuit parameters and oscillator operation was analyzed by measuring the fabricated chips. Then, we designed and developed integrated circuits for a coupled oscillator system that consists of 900 oscillator circuits corresponding with 30x30 pixels of an image, and verified image region segmentation operation using a fabricated chip. We also invented circuit configurations to reduce the effects of device mismatches that inevitably occur in the integrated circuit fabrication.
