This thesis is a detailed description of a neuromorphic visual-motion processing chip and its component parts. The chip is the first two-dimensional silicon retina with a full set of directionselectiv...
A simple formula can be used to design circuits that scale over many decades. Analog or mixed-signal CMOS chips usually require a number of fixed reference currents for biasing amplifiers, determining...
What is the simplest solution for counting objects that cross a field of view? We reduce the problem to detecting localized illumination change on two spatially separated borders. Each circular border...
A new scaling for the standard discrete Luria-Delbruck distribution is provided which leads to a weak convergence result as the parameter of the distribution tends to innity. We show that the stable l...

Abstract ? We present a spike-based saccadic recognition system that uses a temporal-derivative silicon retina on a pan-tilt unit and an aVLSI multi-neuron classifier with a time-to-firstspike output ...
We describe a programmable multi-chip VLSI neuronal system that can be used for exploring spike-based information processing models. The system consists of a silicon retina, a PIC microcontroller, and...
