A Capacitor-Less CMOS Neuron Circuit for Neuromemristive Networks

Abstract

CMOS neuron circuits used to implement neuromorphic chips require extensive circuitry to program the memristive cell, thus eliminating most of the density advantage gained by the adoption of memristive synapses. This paper presents a CMOS neuron circuit that provides a compact and cost-efficient programming interface in which semiconductor capacitors are replaced by a memristive device. The neuron circuit also features an adjustable firing threshold with a strict control of the power consumption during the learning process.
