Abstract (in Japanese) (See Japanese page) 
(in English) The Izhikevich neuron model, which can reproduce various spike activities with a small amount of calculation, is indispensable to construct a new neuromorphic hardware for high order and low power information processing like biological neural network. In the previous report, we proposed a new Izhikevich model neuron circuit based on the discrepancies between the Izhikevich neuron model and the Izhikevich model neuron circuit proposed by Wijekoon and Dudek in 2008, and investigated the dynamics of our proposed circuit by phase plane analysis and SPICE simulation. In this research, we implemented our proposed circuit on an LSI chip using 65nm CMOS technology and compared its dynamics with that of SPICE simulation. By LSI chip measurement, we successfully observed four types of spikes as expected.
