A Neuromorphic CMOS Family and its Application

Silicon circuits that mimic the nervous systems of insects and other animals represent the future of neurocomputing. They can perform various neural functions because the microstructures of a nervous system are replicated on their silicon chips. Since recent functional models of spiking neural networks tend to use spiking neurons, neuromorphic engineers have developed CMOS neural systems with several types of spiking neural circuits to investigate the effect of spike timing and synchrony on the network’s computational properties. In this report, we briefly review our recent collection of neuromorphic circuits, which we call a neuromorphic CMOS family, as well as its application to modern neural networks.
