Design of compensation circuits and techniques for temperature and process variations in a Wibree RF front-end

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
