The stochastic I-Pot: A circuit block for programming bias currents
(Institute of Electrical and Electronics Engineers, 2007)
In this brief, we present the “Stochastic I-Pot.” It is a circuit element that allows for digitally programming a precise bias current ranging over many decades, from pico-amperes up to hundreds of micro-amperes. I-Pot ...

A spatial calibrated AER contrast retina with adjustable contrast threshold
(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 ...

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 3.6 μ s latency asynchronous frame-free event-driven dynamic-vision-sensor
(Institute of Electrical and Electronics Engineers, 2011)
This paper presents a 128 × 128 dynamic vision sensor. Each pixel detects temporal changes in the local illumination. A minimum illumination temporal contrast of 10% can be detected. A compact preamplification stage has ...

A five-decade dynamic-range ambient-light-independent calibrated signed-spatial-contrast AER retina with 0.1-ms latency and optional time-to-first-spike mode
(Institute of Electrical and Electronics Engineers, 2010)
Address Event Representation (AER) is an emergent technology for assembling modular multiblock bio-inspired sensory and processing systems. Visual sensors (retinae) are among the first AER modules to be reported since the ...
