Compact low-power calibration mini-DACs for neural arrays with programmable weights
(Institute of Electrical and Electronics Engineers, 2003)
This paper considers the viability of compact low-resolution low-power mini digital-to-analog converters (mini-DACs) for use in large arrays of neural type cells, where programmable weights are required. Transistors are ...

A spatial contrast retina with on-chip calibration for neuromorphic spike-based AER vision systems
(Institute of Electrical and Electronics Engineers, 2007)
We present a 32 32 pixels contrast retina microchip that provides its output as an address event representation (AER) stream. Spatial contrast is computed as the ratio between pixel photocurrent and a local average between ...

A neuromorphic cortical-layer microchip for spike-based event processing vision systems
(Institute of Electrical and Electronics Engineers, 2006)
We present a neuromorphic cortical-layer processing microchip for address event representation (AER) spike-based processing systems. The microchip computes 2-D convolutions of video information represented in AER format ...
