A Mismatch Calibrated Bipolar Spatial Contrast AER Retina with Adjustable Contrast Threshold
(IEEE Computer Society, 2009)
Address Event Representation (AER) is an emergent technology for assembling modular multi-blocks bio-inspired sensory and processing systems. Visual sensors (retinae) are among the first AER modules to be reported since ...

An AER Contrast Retina with On-Chip Calibration
(IEEE Computer Society, 2007)
We present a contrast retina microchip that provides its output as an AER (Address Event Representation) stream. Contrast is computed as the ratio between pixel photocurrent and a local average between neighboring pixels ...

A calibration technique for very low current and compact tunable neuromorphic cells: Application to 5-bit 20nA DACs
(Institute of Electrical and Electronics Engineers, 2008)
Low current applications, like neuromorphic circuits, where operating currents can be as low as a few nanoamperes or less, suffer from huge transistor mismatches, resulting in around or less than 1-bit precisions. Recently, ...

A Precise CMOS Mismatch Model for Analog Design from Weak to Strong Inversion
(IEEE Computer Society, 2004)
A five parameter mismatch model continuos from weak to strong inversion is presented. The model is an extension of a previously reported one valid in the strong inversion region [1]. A mismatch characterization of NMOS ...
