Abstract :
Prototype neuron and axon circuits for the asynchronous pulse neural network model are fabricated with 1.2 μm CMOS technology and tested. The neuron circuit can function as both of a coincidence detector and an integrator. These opposite neuronal functions can be controlled by changing the internal time constants through the external voltages. The axon circuit, which mimics axonal, dendritic and synaptic delays, realizes pulse delay. The delay time can be continuously controlled by the external voltage
