A low-power adaptive integrate-and-fire neuron circuit

We present a low-power analog circuit for implementing a model of a leaky integrate and fire neuron. Next to being optimized for low-power consumption, the proposed circuit includes elements for implementing spike frequency adaptation, for setting an arbitrary refractory period and for modulating the neuron’s threshold voltage. We present experimental data from a prototype chip, implemented using a
