An Accelerated LIF Neuronal Network Array for a Large Scale Mixed-Signal Neuromorphic Architecture.

We present an array of leaky integrate-and-fire (LIF) neuron circuits designed for the second-generation BrainScaleS mixed-signal 65-nm CMOS neuromorphic hardware. The neuronal array is embedded in the analog network core of a scaled-down prototype high input count analog neural network with digital learning system chip. Designed as continuous-time circuits, the neurons are highly tunable and reco...
