Abstract
We present a silicon neuron that uses shunting inhibition (conductance-based) with a synaptic rise-time to achieve synchrony. Synaptic rise-time promotes synchrony by delaying the effect of inhibition, providing an opportune period for neurons to spike together. And shunting inhibition, through its voltage dependence, inhibits neurons that are late more strongly (delaying the spike further), thereby pushing them into phase (in the next cycle). We characterize the soma (cell body) and synapse circuits, fabricated in 0.25 µm CMOS. Further, we show that synchronized neurons (population of 256) spike with a period that is proportional to the synaptic rise-time.
