The interest for: I: modulation-based NO converters has significantly increased in the last years. The reason for that is twofold. On the one hand, unlike other converters that need accurate building blocks to obtain high res olution: I: converters show low sensitivity to the imperfections of their building blocks. This is achieved through extensive use of digital signal pro cessing - a desirable feature regarding the implementation of NO interfaces in mainstream CMOS technologies which are better suited for implementing fast, dense, digital circuits than accurate analog circuits. On the...

Systematic Design of CMOS Switched-Current Bandpass Sigma-Delta Modulators for Digital Communication Chips discusses architectures, circuits and procedures for the optimum design of bandpass sigma-delta (SD) A/D interfaces for mixed-signal chips in standard CMOS technologies. The book differs from others in the very detailed and in-depth coverage of switched-current (SI) errors, which supports the design of high performance SI chips. The book starts with a tutorial presentation of the fundamentals of bandpass SD converters, their applications in communications and their most...

Desde su nacimiento en la Sierra de Cazorla hasta su desembocadura en el oceano Atlantico, el rio Guadalquivir ha sido a lo largo de la Historia un factor identitario de las comunidades asentadas en torno a el. Los recursos proporcionados por el propio rio, sus afluentes y su extenso valle han contribuido a la supervivencia, bienestar y desarrollo de diferentes culturas. Fruto de esta relacion entre el hombre y el territorio se han ido generando diversos paisajes culturales. No obstante, la situacion politica, economica y sanitaria de los ultimos anos ha provocado que la sostenibilidad de...
