How it works
A compact analog spiking neuron
How to test
Tune 5 external controls (IREFA, IREFB, BIASC, BIASD, and VCORE) and generate firning patterns from Vout.
External hardware
Five adjustable analog sources (voltage or current) for the bias and input pins, an oscilloscope or DAQ for capturing Vout, and a clean analog supply with local decoupling.
