Etude des architectures échantillonnées de réception radio en technologies CMOS submicroniques avancées

Abstract : Due to the development of the third and fourth generation of mobile radio systems, the communication standards will occupy more bandwidth to insure voice, data and multimedia services. In such context, the trend in radio engineering is to integrate all radio and baseband functions on the same die using CMOS process in order to reduce both area and cost of wireless terminals. The evolution of the CMOS process and the miniaturization of the MOS transistors have made analog design more and more complex, new parasitic effects rise, additional dynamic range constraints due to supply voltage scaling pop up and also noise coming from the more growing digital circuits increases. Recently, new type of radio receive solutions has appeared, in such receivers the RF signal is directly sampled and then processed using only switched-capacitor elements. The purpose of the present PhD thesis work is to quantify the scalability of the sampled radio receive architecture, by studying the impact of the parasitic effects on the radio performance of the solution. The scalability benchmarks that were considered in this work are the reconfigurability, immunity to parasitic effects, adaptation to supply voltage scaling, area, power consumption and ease of designing. In order to face real scalability issues, a porting of an existing sampled radio receive architecture from CMOS 65 to 45nm has been realized. The measured performance of the designed circuit has shown good performance and has brought a first element of answer to the scalability issue of the sampled architecture.
