Tesis doctoral de \u00ed\u00f1igo Adin Marcos <\/strong><\/h2>\n

La creciente necesidad de transmitir datos en los entornos laborales y personales est\u00e1 promoviendo la incre\u00edble proliferaci\u00f3n de los est\u00e1ndares inal\u00e1mbricos. Algunos de los m\u00e1s comunes y m\u00e1s utilizados, como bluetooth y wifi ieee 802.11 b\/g, tienen asignado sus espectro frecuencial en la banda libre ism de 2.4 ghz. El incremento del n\u00famero de usuarios y aplicaciones y el aumento de las tasas de bits necesarios en las m\u00e1s modernas aplicaciones multimedia han propiciado por una parte el traslado de los est\u00e1ndares a bandas frecuenciales m\u00e1s altas, y por otra la integraci\u00f3n de m\u00faltiples est\u00e1ndares en un solo terminal. Wifi en su versi\u00f3n ieee 802.11 a y wimax ieee 802.16 a\/e son los est\u00e1ndares l\u00edderes en las redes de comunicaciones inal\u00e1mbricas de gran ancho de banda y est\u00e1n ambos alojados en la banda libre de 5 ghz de u-nli. El bajo coste de producci\u00f3n y el bajo consumo de potencia deben ser los referentes para el dise\u00f1o de receptores y emisores para estos est\u00e1ndares.El desarrollo de la tecnolog\u00eda cmos para la fabricaci\u00f3n de circuitos integrados, principalmente orientada a circuitos digitales, ofrece el mejor precio y el m\u00e1s r\u00e1pido desarrollo del producto. Es por esto por lo que el mayor reto para los dise\u00f1adores de circuitos integrados para radiofrecuencia es la integraci\u00f3n total en receptores y emisores, hecho que se ve favorecido con los constantes avances de esta tecnolog\u00eda para las altas frecuencias. La minimizaci\u00f3n del consumo de corriente permite la integraci\u00f3n de m\u00faltiples aplicaciones en los modernos terminales de comunicaciones manteniendo sus prestaciones de duraci\u00f3n de bater\u00edas. En lo concerniente al dise\u00f1o de circuitos integrados de radiofrecuencia para receptores, la disminuci\u00f3n del consumo se ha afrontado desde dos puntos de vista: la selecci\u00f3n de la arquitectura del receptor y las mejoras aportadas al dise\u00f1o concreto de cada bloque. El objetivo principal de este trabajo de investigaci\u00f3n es el dise\u00f1o y la caracterizaci\u00f3n de una serie de circuitos integrados para una cabecera de recepci\u00f3n de un terminal de bajo consumo. Se ha utilizado para tal efecto un sistema de simulaci\u00f3n para la banda de 5 ghz de u-nll tanto en su dise\u00f1o como en la validaci\u00f3n posterior de la arquitectura y de las t\u00e9cnicas empleadas. %&\/Este trabajo refleja la adecuaci\u00f3n de la arquitectura de baja frecuencia intermedia para las exigentes especificaciones comunes extra\u00eddas de los tres est\u00e1ndares considerados en la banda objetivo. Los circuitos integrados dise\u00f1ados y caracterizados han sido el amplificador de bajo ruido, el mezclador y el oscilador controlado por tensi\u00f3n. Adem\u00e1s se ha dise\u00f1ado el divisor de frecuencia del lazo del oscilador local. La composici\u00f3n de cada bloques ha sido detalladas, as\u00ed como las t\u00e9cnicas espec\u00edficas empleadas para conseguir un m\u00ednimo consumo de corriente global. the increased need for data transmission within home and office environment has created the remarkable proliferation of the wireless standards. Some, such as bluetooth and ieee 802.Llb allocated in the ism 2.4 ghz band, are a necessary and integral part of every day living. However, this very fact has resulted in an ever increasing number of users and applications. There is an augmenting demand being made on higher data rates which have culminated in the migration of the most powerful communicati\u00f3n standards to higher frequency bands and the integration of multiple standards in the modern mobile devices. Wifi in its ieee 802.11a version and wimax ieee 802.16a\/e are the leading standards of the new era of reliable broadband-connected wireless networks and both are allocated in the unlicensed 5 ghz u-nii band. The low cost and low power consumption must be key points of reference within the design of receivers and transceivers for these standards. The development of the digital oriented cmos \u00edes, offers cmos as the lowest cost and the most effective time-to-market technology. The design of cmos rf front ends allows the challenge of the full digital and analog integration aim of the modern receivers and transceivers. In addition, constant advances in the fabricati\u00f3n of this process provide better performances for the high frequency rf design. The minimization of power consumption allows the integration of multiple applications in mobile devices and the extension of their battery life. Regarding the rf front end, the duty of lowering the required current is approached from two leveis: the architecture selection and the improvement on the blocks design. He main objective of this work is the design and characterization of a set of integrated circuits for a low power mui ti standard rf front end. A simulation system for the 5 ghz u-nii band has been utilized to validate the decisions and techniques adopted in this work.%&\/This work shows the low if architecture as suitable for the exigent common specifications extracted from the three standards considered in the objective frequency band. The integrated circuits designed and characterized are the low noise amplifier, the mixer and the voltage controlled oscillator of the local oscillator. Furthermore the high frequency dividers of the lo feed forward loop have also been designed. The four blocks composition is explained and the specific techniques employed to fulfi 11 the requirements with a minimum current consumption are detailed<\/p>\n
