Abstract
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 standard 1.5 μm CMOS process.
