Simulation of a 100% analog neuron with current processing circuit

Abstract

A 100% analog neuron, implementable in CMOS1.2pm technology, was designed and simulated. The neuronconsists of simple current processing circuits, right from thesynapses' inputs to the axon's output. Only the weight inputis in voltage form, to achieve the fastest possible response. The neuron has an adaptive firing threshold, as well as anautonomous, local, non-supervised learning circuit.
