Learning under hardware restrictions in CMOS fuzzy controllers able to extract rules from examples [Article]

Vidal Verdú, Fernando; Navas González, Rafael; Rodríguez Vázquez, Ángel Benito (Universidad de Granada. Departamento de Ciencias de la Computación e Inteligencia Artificial, 1996)
Fuzzy controllers are able to incorporate knowledge expressed in if-then rules. These rules are given by experts or skilful operators. Problems arise when there are no experts or/and rules are not easy to find. Author's ...

A 2.5MHz 55dB Switched-Current BandPass ΣΔ Modulator for AM Signal Conversion [Presentation]

Rosa Utrera, José Manuel de la; Pérez Verdú, Belén; Medeiro Hidalgo, Fernando; Rodríguez Vázquez, Ángel Benito (Institute of Electrical and Electronics Engineers, 1997)
We present a Switched-Current (SI) fourth-order bandpass ΣΔ modulator IC prototype. It uses fully-differential circuits in 0.8μm CMOS technology to obtain a Dynamic Range (DR) larger than 55dB at 2.5MHz center frequency ...

A 176x144 148dB adaptive tone-mapping imager [Presentation]

Vargas Sierra, Sonia; Liñán Cembrano, Gustavo; Rodríguez Vázquez, Ángel Benito (Society of Photo-Optical Instrumentation Engineers, 2012)
This paper presents a 176x144 (QCIF) HDR image sensor where visual information is simultaneously captured and adaptively compressed by means of an in-pixel tone mapping scheme. The tone mapping curve (TMC) is calculated ...

High-order cascade multi-bit Σ∆ modulators for high-speed A/D conversion [Presentation]

Río Fernández, Rocío del; Medeiro Hidalgo, Fernando; Pérez Verdú, Belén; Rodríguez Vázquez, Ángel Benito (Universidad Carlos III, 1998)
The use of Sigma-Delta (Σ∆) modulation for analog-to-digital conversion (ADC) in the communication frequency range is evaluated. Two high-order multi-bit architectures are proposed to achieve +12-bit dynamic range at ...

A CMOS vision system on-chip with multicore sensory processing ar- chitecture for image analysis above 1,000F/s [Presentation]

Rodríguez Vázquez, Ángel Benito; Castro, Rafael; Jiménez Garrido, Francisco José; Morillas, Sergio (Spie, 2010)
This paper describes a Vision-System-on-Chip (VSoC) capable of doing: image acquisition, image processing through on-chip embedded structures, and generation of pertinent reaction commands at thousand’s frame-per-second ...

High dynamic range adaptation for ROI tracking based on reconfigurable concurrent dual-sensing [Article]

Fernández Berni, Jorge; Carmona Galán, Ricardo; Río Fernández, Rocío del; Rodríguez Vázquez, Ángel Benito (Institution of Civil Engineers (Great Britain), 2014)
A single-exposure technique to extend the dynamic range of vision sensors is presented. It is particularly suitable for vision algorithms requiring region-of-interest (ROI) tracking under varying illumination conditions. ...
