Simple Analogue Vlsi Circuit Of A Cortical Neuron

This paper presents a novel analogue VLSI circuitry that reproduces spiking and bursting firing patterns of cortical neurons, using only 14 MOSFETs. The circuit provides a basic building block for the development of neuromorphic architectures. It enables implementation of many neurons in a single silicon chip while exhibiting flexibility in obtaining different types of adaptive and oscillatory neuron behaviours, by simply adjusting the biasing voltage. ne simulation results, using a 0.35um CMOS technology, are presented.
