Amplificateur de puissance autonome pour applications OFDM et beamforming de la 5G aux fréquences millimétriques en technologie CMOS avancée

Abstract : In order to meet the growing demand for more connected objects and higher data rates,the fifth generation of mobile network (5G) will be deployed. To address thesechallenges, the 5G will use beamforming to improve the transmission quality and extendthe network coverage. Due to the lack of available RF spectrum below 6 GHz, the mobileindustry is studying millimeter wave frequency bands in particular around 28 GHz. Theuse of CMOS technology for 5G applications is promising for the 5G mass market,especially nowadays the miniaturization of CMOS transistors allows competitiveoperation at millimeter frequencies. To meet all the expectations of the 5G especially interms of reliability, new breakthrough ideas, with the self-healing and the selfcontained,allow to use all the benefits of CMOS technology to the maximum whileoffering reliable operation for the amplifier. Within the framework of self-healing andself-contained, several circuits are integrated on silicon such as an amplifier integratedwith a totally non-invasive power detector for self-healing and a balanced self-containedamplifier.
