Color Tone-Mapping Circuit for a Focal-Plane Implementation
(IEEE, 2018)
In this article, we present a review of the driving principles and parameters of a previously reported focal-plane tone-mapping operator. We then extend it in order to include color information processing. The signal ...

Design Considerations for an Automotive Sensor Interface Sigma-Delta Modulator
(Institute of Electrical and Electronics Engineers, 2003)
The Sigma-Delta Modulator presented in this paper contains a programmable-gain input inferface to accommodate the output signal level of a variety of automotive sensors. We show that this characteristic can be efficiently ...

On the design of a sparsifying dictionary for compressive image feature extraction
(Institute of Electrical and Electronics Engineers, 2015)
Compressive sensing is an alternative to Nyquist-rate sampling when the signal to be acquired is known to be sparse or compressible. A sparse signal has a small number of nonzero components compared to its total length. ...

A multiplexed mixed-signal fuzzy architecture
(Institute of Electrical and Electronics Engineers, 1998)
Analog circuits provide better area/power efficiency than their digital counterparts for low-medium precision requirements. This limit in precision as well as the lack of design tools when compared to the digital approach, ...
