Synthèse de fréquence multi-bandes couvrant les ondes millimétriques pour les applications WiFi-WiGig

摘要

The works presented in this manuscript focus on the realization of a millimeter frequency synthesizer meeting the needs of the WiGig-Fi convergence. A first study was conducted to define a suitable low-power frequency synthesizer archi-tecture for WiFi and WiGig standards. All of the PLL components are subsequently detailed, highlighting the 28nm CMOS FDSOI technology benefits. Then, a study of low power millimeter broadband VCO is presented, highlighting a design methodology related to the 28nm CMOS FDSOI technology. Finally, various solutions are proposed in order to improve the PLL performances, with the incorporation of slow wave VCO, or injection locked ring oscillators.
