Using multi-threshold threshold gates in rtd-based logic design. A case study
(Laboratoire TIMA, 2007)
The basic building blocks for Resonant Tunnelling Diode (RTD) logic circuits are Threshold Gates (TGs) instead of the conventional Boolean gates (AND, OR, NAND, NOR) due to the fact that, when designing with RTDs, ...

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 ...

Resonation-based cascade ΣΔ modulator for broadband low-voltage A/D conversion
(Institute of Electrical and Electronics Engineers, 2008)
cascades while presenting very relaxed output swing requirements and, subsequently, high robustness to non-linearities of the amplifiers. In addition, the use of loop filters based on Forward-Euler integrators, instead of ...

Estudio comparativo de los divisores en la tecnologías CMOS nanométricas
(Instituto Superior Politécnico José Antonio Echeverría (CUJAE), 2009)
Son varios los algoritmos de divisores propuestos para su realización en hardware, sin que haya un ‘mejor divisor’. La búsqueda de un diseño óptimo para cada aplicación específica hace que sea indispensable la investigación ...
