Abstract :
A BiCMOS, asynchronous, pulse-stream neuron chip and a CMOS, asynchronous, pulse-stream synapse chip have been designed. The neuron chip uses novel circuitry to implement an accurate sigmoid transfer characteristic. The synapse chip uses a new pulse-stream implementation of the differential amplifier and requires only five transistors to produce a linear multiplier. Training has been performed in software using ideal models of the neurons and synapses.
