This thesis is a partnership between the BL TVFE of NXP Semiconductors and ESIEE. Its goal is to provide a solution to multi-channel reception for cable network. This is linked to the problematic of broadband digitization. In the first part, the state-of-the art of ADCs, parallel architectures (TI and HFB) and sampling methods (bandpass sampling and complex sampling) is recalled. Then we study an architecture called RFFB with a bank of analog filters and a bank of ADCs. We try to reduce the constraints on ADCs, especially the sampling rate with the different sampling. We propose an interesting solution to broadband digitization and compare this solution to a challenging wideband ADC, using the cost function we introduce. This architecture h...
