PUT-based Integrate-and-Fire Neuron Experiment
This analog electronics project uses a programmable unijunction transistor (PUT) to simulate an integrate-and-fire neuron, experimenting with variations of pulse-width and frequency of the input spike train to see how they affect when the neuron fires. Planned next step is adding a resistor to bleed charge from the timing capacitor to make it a leaky integrate-and-fire neuron, as part of the author's explorations in neuromorphic and analog computing.

“I've been doing a bunch of stuff with using a PUT[1] to simulate an IF (Integrate and Fire) neuron[2]. Right now I'm experimenting with variations of pulse-width and frequency of the input spike train, seeing how that affects when the "neuron" fires. In a future step I'll add a resistor to bleed off some of the charge from the timing capacitor, to make it more of a "Leaky Integrate and Fire" neuron.”
