Abstract
El projecte analitza l'impacte de variacions de temperatura i procés sobre blocs d'un capçal RF per Wibree. Els primers dissenys dels circuits, realitzats en tecnologia CMOS, estan fets i l'objectiu del treball es fer modificacions per permetre el bon funcionament en un rang de temperatura específic i considerant variacions de procés. Es proposen diverses solucions per reduir les variacions de les característiques dels circuits : LNA ,mixer i VCO. El projecte es basa en tecnologia CMOS per RF de Seiko-EPSON The work started after the development of first designs of a low noise amplifier (LNA), an active
and a passive mixers and a voltage controlled oscillator (VCO). The main objective was to study
the impact of temperature and process variations in those first designs and perform the
necessary compensation or correction regarding possible performance degradation. Thus, the
study included in this project intends to analyze the impact of the variations on the technology
and to define possible and feasible techniques to remove or decrease variations on the
concerned block of the RF front-end
