The work presented in this Ph.D. dissertation deals with the design of a wideband and accurate Analog-to-Digital Converter (ADC) able to digitize signals of different wireless communications standards. Thereby, itresponds to the Software Defined Radio concept (SDR). The purpose is reconfigurability by software andintegrability of the multistandard radio terminal. Oversampling (Sigma Delta) ADCs have been interestingcandidates in this context of multistandard SDR reception thanks to their high accuracy. Although they presentlimited operating bandwidth, it is possible to use them in a parallel architecture thus the bandwidth isextended. Therefore, we propose in this work the design and implementation of a parallel frequency banddecomposition...
