LVDS interface for AER links with burst mode operation capability
(IEEE Computer Society, 2008)
This paper presents the design and simulation of a serial AER LVDS communication link. It converts data from classical AER parallel bus with a 4-phase handshaking protocol into a bit stream which is transmitted serially ...

Current-mode fully-programmable piece-wise-linear block for neuro-fuzzy applications
(Institute of Electrical and Electronics Engineers, 2002)
A new method to implement an arbitrary piece-wise-linear characteristic in current mode is presented. Each of the breaking points and each slope is separately controllable. As an example a block that implements an N-shaped ...

A Physical Interpretation of the Distance Term in Pelgrom’s Mismatch Model results in very Efficient CAD
(IEEE Computer Society, 2007)
In 1989 Pelgrom et al. published a mismatch model for MOS transistors, where the standard quadratic deviation of the mismatch in a parameter between two identical transistors, is given by two independent terms: (1) a ...

Programmable kernel analog VLSI convolution chip for real time vision processing
(IEEE Computer Society, 2000)
A neural architecture that implements a programmable 2D image filter has been presented. The architecture allows to implement any 2D filter F(p,q) decomposable into x-axis and y-axis components F(p,q) = H(p)V(q) such that ...

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 ...
