A 1.6-fJ/Spike Subthreshold Analog Spiking Neuron in 28 nm CMOS
This paper presents a 1.6-fJ/spike subthreshold analog Leaky Integrate-and-Fire neuron fabricated in 28 nm CMOS, which achieves a 300 kHz spiking frequency at 250 mV and demonstrates 82.5% accuracy on the MNIST dataset when used in a quantized Spiking Neural Network, validating its potential for energy-efficient embedded machine learning.
