Abstract :
We present an implementation of a programmable axonal propagation delay circuit which uses one first-order log-domain low-pass filter. Delays may be programmed in the 5-50ms range. It is designed to be a building block for time-delay spiking neural networks. It consists of a leaky-integrate-and-fire core, a spike generator circuit, and a delay adaptation circuit.
